Hi Jags, no we don't sell them, try http://wooshbikes.co.uk/

Please note Thorn frames, forks and many components are not tested to EN15194.

There are many other compliance issues with EN15194, this means if you did convert it and didn't adhere to all of the regulations, the complete electric assisted Thorn may then need to be registered, insured and taxed as a motor vehicle. In this case, you will also need a driving licence, and you must wear a motorcycle helmet.

Post by: Andre Jute on February 07, 2019, 01:18:57 am
Depends which one you have in mind, Jags. I've bought both the front-drive 8FUN Bafang QSWK and the centre 8FUN Bafang BBS-01 in Britain, each time in a kit requiring nothing else and no work to fit the kit that you cannot do with a standard bicyclist's toolkit. In each case it was a happy transaction and I thought the premium for avoiding possibly swingeing import charges on importing from China instead well worth the price. Both dealers, Ecosmobile and Eclipsebikes, are recommended for going the extra mile for me.

This is the front motor: https://www.ebay.co.uk/itm/8Fun-Ebike-Electric-Bike-Conversion-Kit-36V-250W-20-26-700C-Wheel/190694074560?hash=item2c6640a8c0:m:mk--EsX27sxmVEmXYYN2hxQ:rk:41:pf:0 which is complete, including the battery.

Bafang centre-motor kits here: http://eclipsebikes.com/index.php?cPath=26_27. All the kits on this page are complete bolt-on jobs. This one is legal in Ireland: http://eclipsebikes.com/product_info.php?products_id=15.

Batteries for the centre-motor kits here: http://eclipsebikes.com/index.php?cPath=30_31. This is the battery I have and it still seems a good balance between capacity and price: http://eclipsebikes.com/product_info.php?products_id=101

Two things to avoid: Don't try to buy the components separately, but do buy a complete kit. Don't try to build your own battery because complicated, sophisticated control and charge electronics are required if the thing is not to be dangerous.

I were you, I'd try to borrow for a week or two a pedelec of any kind that has been sold in Ireland, so you can understand why it is inadequate for a serious cyclist; for instance, its assistance declines just when you need it most, when you're going uphill. It's for this reason that you should buy and fit your own kit, like those above, with selectable and programmable response curves chosen by buttons under your thumb and a throttle that overrides everything.

What your average electric bike consumer wants in an electric bike, and what a real cyclist wants from an electrified bike are two very, very different things.

What I've been telling y'all for years now... Those Bafang 8FUN centre motors and associated hardware and software really are the best, and pretty near the bottom of the price list too, very good value.

Since I was already on Youtube, I watched the next video as well, about an entirely different class of e-bike, the e-mountainbike, a test of a cheap one against an expensive super bike. Nothing to do with touring bikes, but amusing. Thanks for that as well.

It depends which kit you buy and who you buy it from, Anto. With the front wheel motor kit from Ecosmobile, you get the battery in the kit for 400 pounds and change, so the entire installation costs including delivery costs well under 500 Euro.

It's just happenstance that I bought my Bafang centre motor kit from people who sell the motor and controller electronics and wiring as one kit, and the battery separate. I found them the cheapest in total, and their control electronics weren't crippled, and I judged after speaking to them on the phone that they were technically competent, which couldn't be said for some of the clowns viewing ebikes as an opportunity to make a quick buck.

But if you look around on the net, you'll find a centre motor kit that comes complete with a battery. Whether it will be cheaper in total than the people I referred you to, is another matter. A good place to start is https://www.pedelecs.co.uk/forum/ (https://www.pedelecs.co.uk/forum/) -- but don't start running after every short-lived enthusiasm of the people there; that's a sure way to spend your money and get something short-lived in return; in addition, some of the people there are UK sellers of certain brands and go off at half-cock at every unproven new-new-new piece of soon-to-be-yesterday's-news. Stick to the two Bafang motors I've identified for you (the 8FUN QSWXK kit Ecosmobile sells on EBay or direct and the BBS1 Bafang 8FUN motor Eclipsebikes sell and for which they also supply suitable plug and play batteries for good prices), which are the common motors among other members of this forum for the good reason that they all have their brains in gear and a tight hand on their wallets.

Note that I trashed my QSWXK kit after 3500km. But I'd been expecting something like that: I just never ride on the flat, and the hills of West Cork killed it; I thought I had good value out of it as an initial experiment to discover whether I liked the experience or should give up cycling altogether. The motor could in theory be rebuilt with steel gears instead of the nylon gears I melted, but the motor itself is the cheapest part of the kit, and the control electronics also melted down, so I didn't bother, just went to the BB motor. The BB motor is a stronger item, which is why it costs more. Mine has already outlived the QSWXK and is going strong. If you read roundabout on the forum here, you will discover that some other ebike owners and I discussed the matter and came to the conclusion that an ebike motor is a consumable item: you can't expect it to last as long as the bike, and you really must look after the battery carefully.

However, if you want to buy a 36V 250W Bafang centre motor kit without a battery, I'll be happy to give you my old kit's battery, which was in good nick when I put it away. It's 9Ah, which should give you a reasonable range. It fits in the water-bottle space on the downtube; it has its own quick release rack with a lock and can be charged on or off the bike. Let me know if you're interested -- and before you actually spend money on the rest of the kit! -- and I'll take it out and put a meter on it to check precisely what sort of nick it is in. You'll need someone competent in electrics to join the wires from the battery cradle to the wires from the motor, but I'll send you the colour codes; I did it myself.

Andre your a gent but i can't spend money at the moment thanks all the same. ;)
im totally convinced the ebike bafang is for me if it fits my bottom bracket shell and had perfect chain line it would be fantastic,i just need help with hills getting up them ;D.

would i need to change to flat bars don't fancy that to be honest  then again might not be to much of a disaster,just that i got a custom fit for my audax  and don't want to change anything ..

anyway thanks Andre ill get back to you in the summer time.

Post by: Andre Jute on February 12, 2019, 12:55:58 am
Whether the chainline of the Bafang centre motor will be good on your bike depends on the rear end of your bike, Jags. The kit comes with a dished chainring which part of the drive end of the motor fits into. It limits you in the smallest chainring you can go for (standard supplied with the kit is 46T but 42T will fit though I went down only to 44T) but matches the 54mm Rohloff chainline out of the box or with only minimal shimming, depending on your bottom bracket's fitting precision -- cross my heart and hope to die. You can buy deeper-dished chainwheels but I happen to like steel chainrings and there's nothing wrong with the OEM chainrings, so I stuck to those.

The tidy fascia and control button cluster and thumb-throttle can be fitted anywhere on any kind of handlebar you prefer, and you don't even have to fit all of them because each one is separately cabled with little waterproof plugs and sockets. If you want to build a stealth-bike, all you need to fit is the control button cluster, which is all black, unlabelled, and less than two inches to a side, and then you can leave off the  thumb throttle and fascia (which doesn't control anything; it just reports speed, etc). The controller buttons switch the power on and off, rolls the bike for you when you're parking it, gives you access to 9 levels of assistance (or you can choose 3 levels or 5 levels -- it's like having a multi-gear overdrive) when you pedal, switches the fascia light on and off for when it is dark, and gives you access to the reporting functions of the fascia (which is much like a bike computer). The throttle, if fitted, overrides the other settings temporarily. There is also a brake cutout which you should fit; it puts motor in neutral when you apply either brake.

Apologies re jumping on someone else's thread - I am looking at fitting a Bafang mid drive kit to my wife's Sherpa and am after some advice on how this will change things.

Let me know if this would be better put in a separate thread but my initial concerns are:

Chain-wheel size - given that she will be loosing the triple front chainwheels, and the Bafang kits come with ~46 tooth singles, will she end up with a very different cadence for the same speeds? 
How do the brake levers compare with the Thorn fitted Shimano levers - she has smallish hands and is not keen on long reaches for the brakes.

Given that she wants assistance rather than extra 'go' I'm assuming a 250W kit will be ok and give better battery life/range - is that reasonable?

i think you can get an upgrade chainring .im a twiddler meself usually ride 39 up front only use the 50 when i going well or down hill.so not really sure what would be best to buy.
better off getting the 750 watt more power on the hills i would imagine.

Andre would be a good man to advise ;)

Post by: sdg_77 on February 13, 2019, 05:43:15 pm
Thanks Anto - we both spend most of our time on the middle chainrings,  and only use the big-dog for wooshing down hills.

No idea what to think about the motor power.  I am an electrical engineer so I'm assuming a bigger motor will have better current handling capacity in the controller and so be more reliable, at a cost of some weight and of course cash.
Against that, a smaller motor ought not to drain the battery so quickly, or get up hills quite so well.

sdg if i had the money (i don't) i'd have that bafang motor on my Audax tomorrow ;)
my 2 bikes have been gathering dust this past year due to back pain i find it impossible to get up hills and theres plenty of them where i live.

i'm not to worried about speed but saying that i'd want that motor to hit 25mph on the flat .
average speed over say 40 to 50 miles 13mph.
and i wouldn't want to change my drop bars,another concern would be all that wiring,i'm a geek for keeping my bikes in pristine condition so wouldn't want wires hanging about spoiling the look of my bike  :'(
saying that tho,i'd give one of the grand kids away for that bafang conversion. ;D

Post by: Andre Jute on February 14, 2019, 06:03:16 am
Steve, have you considered fitting a Rohloff hub gearbox to your wife's bike? It has 14 usable gears, spaced about 13% apart, 526% range, and can be geared as low as she can keep her balance; we have some stump-puller transmissions on the forum here. Personally, for a tourer (and for a utility bike and a commuter for that matter) I consider a Rohloff a better first option, with fewer limiting factors, than going straight to an electrified bike.

If a Rohloff is out of the reckoning, I'll answer your questions:

First of all, forget anything but the 250W* motor. With a bigger motor comes a bigger battery consumption (or less range), more weight that has to be dragged along. Secondly, borrow or rent an electric bike to ascertain if your wife will be happy pedalling along the extra weight when the motor is not in use. If you fit a 750W motor, your wife will have to drag a battery three times as large, and sooner or later the police will take an interest. And forget about 25mph too; sure, I've ridden up there on occasion, but I have an humongous battery, and I'm never further than 20-25kph from home unless I know that I'll sleep next to a plug that night. The other number Anto threw out, averaging 13, is good, but it is 13-15kph not mph, which is what my pedal pals and I average over the course of a year (we live in countryside that is all hills, all the time -- the few pieces of flat roads carry lethal amounts of traffic at lethal speed, and the hard shoulder, or any shoulder, keeps disappearing). You have to approach electrifying a bike realistically, even humbly; it just isn't a roadracer's option, which is what Anto appears to think!

The Bafang BB motor generally comes with a 46T chainring but that isn't set in stone; maybe your supplier will swap it out for you. In any case, a different tooth-count chainring is under a tenner from China, and, since it is steel, you'll never wear it out. I have a 44T chainring on my bike, which appears to me to be the smallest the Bafang BB motor will take that will also suit a Chainglider, an amenity I insist on on all my bikes. The chainring is dished to claw back tread width, so if you want another type of chainring, it could be an expensive custom job; some ali chainrings are available but while the Italian ones are beautiful, they're also about a fifth of the price of the complete kit. I'm well satisfied with the steel chainring (it's 20 years since I last bothered with a fast-wearing ali chainring). Before I fitted the centre motor my transmission was 38x16T (I in the middle of a couple of rounds of heart surgery), and I thought that I would use the motor more because of the 44T chainring, but that hasn't happened and the longer legs have turned into a good thing for my health too.

If your wife cannot or does not want to pull a 46 or 44T chainring, there's an alternative that lets her keep her entire transmission, including the front derailleur: front hub drive. If that means she loses her hub dynamo, you can get B&M front and rear lamps that operate off the motor battery (36V nominal). See http://coolmainpress.com/BICYCLINGbuildingpedelec5.html
The front motor I had was the Bafang QSWXK and you can see here how I fitted it:
http://coolmainpress.com/BICYCLINGbuildingpedelec1.html
It comes as a full kit including an excellent battery, well-scaled to the motor, from the vendor I recommend. A complete installation of the front motor, including new lamps, came out a third cheaper than the centre motor installation, in both cases including the battery. The front motor needs a bit more care than the centre motor: I burned mine out in 3500km, but my bike carries more weight -- my painting gear is on it all the time -- than most fast tourers would contemplate, and I have a heavy throttle thumb. It was rebuildable but I bought it only as an experiment, so I didn't bother, just went straight for a centre motor better scaled to my requirements and habits, which has now exceeded the mileage of the front motor without any sign of stress. For a motor to last a very long time, you may wish to swap out the nylon gears for the available and pretty cheap steel gears.

I've no idea how the kit brake levers compare with the Thorn-supplied brake lever; I just left those brake levers in the box because I bought special hydraulic brake interrupters.

* And forget what an electrical engineer knows about the relationship of Watt to horsepower etc. The CE regulations allow the manufacturer to say how strong the motor is, and nobody checks on it. As an associated fact: These Bafang motors are so popular because of their heritage, their origins in the famous offroad BPM motor, which started at about a real 350W but was optimized for torque and so "appeared" to be a 250W motor. Torque is by far more useful than Watt as a measure of the utility of a motor for a tourer's bike. Watt is useful only for the speed freaks.

I just folded up the extra wiring and tie-wrapped it to the handlebars. I make a point of swooping through the forecourt of the garage where all the cafe racers sit outside in their latex with their lattes and their shiny unused bikes so that they can see all that surplus wiring. Sometimes I slow down to enjoy the grimaces settling over their faces longer.

Seriously, Anto, if that is your criterium, sorry, I mean criterion, you'd better give up the idea of building an electric bike, because the only bikes that have hidden wiring are the ones designed from the ground up as electric bikes, and you wouldn't want to be seen dead on one of those with their obviously ali, obviously thickened tubes, besides which their motors and controls will be crippled, which isn't what you want by a mile. You just can't build a electric bike on a steel road frame without several visible wires running back and forth. On my Trek Smover, the full auto Di2 bike, I got so fed up with cables I couldn't shorten (too many wires inside, too fine for my soldering skills), that one day I took a piece of spiral computer-cable tidy from my study to the bike, and just folded the surplus cable away in it; it worked because the spiral cable was the same colour as the bike. Scroll down to the cockpit view for a good look at the cable tidy:
http://coolmainpress.com/BICYCLINGsmover.html
With the centre motor you have several more cables than with the Smover or the front motor. True, they're modular (loose cables with waterproof plugs) and if you give up the unit they connect, for instance the fascia, you also lose the cable, but some things are essential for the operation of the bike, like the button cluster.

If a Rohloff is out of the reckoning, I'll answer your questions:


Many thanks Andre - a Rolhoff is out of the reckoning - Gill is looking for assistance rather than extra gears.

I'll go through your notes over the next day or so - but thank you for the reply - I have been away for a few days and hadn't seen it.
Some of the YouTube videos I have found point to chain rings and devices to keep the chain in place so I'll look at the chainglider too.

[url]https://www.youtube.com/watch?v=rcYVyuDC6e8&t=6s[url]

This video (Australian) shows a Lekkie chain ring with a different tooth profile so I might take a look at one of those if I get the opportunity.
The extra brake sensors look to be the way to keep the original brake levers too  :)

Gill is around 60kg so I'm expecting that might give her a little extra range from the battery.  I'll just have to check what will fit into her 48cm frame.

sdg.

Post by: Andre Jute on February 17, 2019, 11:10:12 pm
The question in fitting a BB motor to a small bike is usually ground clearance. The Bafang BB motors can be swivelled around the BB shell until snug to the downtube to give a bit more ground clearance.

the chainring that comes with that kit isn't for this kid looks like something cheap you would see on a  kids bike Sorry Andre :-\....

Into, I find it good enough, and it replaced a highly polished Surly stainless ring that I was very fond of. The Bafang chainring has the right chainline for the Rohloff, works a treat, and it lasts and lasts; I also had excellent experience with an Indian steel chainring on another bike when I told the supplier just to put on the cheapest crankset he had until I decided what would suit the aesthetics of the bike; I liked it so much I rode on it c8 years until I found Stronglight crankset I liked. If you hate the Bafang OEM chainring, sand it down lightly and paint it with aerosol enamel, bake it in your wife's oven, and you have a custom job.

Well - that was interesting ....

Finally ordered the Bafang Kit from Eclipse once they had them in stock,  fitted it to the bike with a 44 toth chainwheel and had problems with the chain a new Shimano HG riding up onto the top of the teeth and then falling off.

Put the original 48 tooth on, without the chain guard and all is ok - chain guard on and still ok!

So far the bike has just been to the end of our street and back - should be able to try a longer ride soon(ish)

Thanks to everyone for their help - particularly Andre.

Might try a 36 tooth bling ring if all is ok as I think that will be closer to the original middle chainring where Gill did most of her pedalling.

I'm not enamoured of the chainguard that come with the Bafang BBS. It might be OK if your wife cycles only in lycra, no exceptions, but the minute she starts cycling in street clothes, it becomes a danger. I invariably cycle in street clothes and chucked off the chain guard on the first day of what was going to be a week's trial -- after it twice ate the bottom of my khakis and nearly caused a gravel rash incident or worse in the space of only minutes, within pushing distance of home; it was just as well I had started uphill and was going slowly. I fitted the Chainglider on standby for the next week's test, and never looked back.

Thanks to everyone for their help - particularly Andre.

Happy to help. One hand washes the other.

Might try a 36 tooth bling ring if all is ok as I think that will be closer to the original middle chainring where Gill did most of her pedalling.

I haven't looked into the bling rings recently as I'm perfectly happy with Bafang's OEM fit and forget steel ring. After over 10K of what I expected to be hardwearing experiments, like running chains for their entire life on the factory lube, no cleaning or extra lube ever, inside a Chainglider, the steel ring appears unmarked. My kick is a maintenance-free, no bother bike you just get on and ride when the notion takes you, or the rain stops for an hour, so the steel ring and I are a match made in heaven.

However, be sure the 36 tooth ring is well made in both the machining (not cut too thin "around the corners" to get the dish depth) and the engineering senses (not so much offset that it wrecks the bottom bracket bearings which are part of the Bafang motor and likely to be a pain to rebuild, etc) before you splash out many shekels for it. I seem to recall that a 38T ring from an Italian firm which looked almost as heavily made and long-lasting, in the photos anyway, as the flat, thick Thorn OEM ring well-known here, about a hundred euro landed in these islands, was at one stage the minimum tooth count offered for precisely these reasons.

Something else you might consider is that the control circuitry that came with the BBS, besides the throttle, has nine different speeds or levels of pedelec assistance, acting like a gearbox in itself (you can group these so that the thing appear appears to have only 5 or 3 electronic gears) which, if mounted under her thumb, can be used to keep her cadence in the range she's used to, and to give the rear gear cluster some protection against the torque of the motor. I came to cycling too late to learn a butterfly cadence, so I mash through, using my heart rate monitor like other cyclists use a cadence meter, together with the 5 electrical gears I have set plus the top half of the Rohloff gears to control my exertion to within one heartbeat. And of course for downhill thrills in the Rohloff's three overdrive gears.

Yes - we're definitely both pedal spinners so getting down to more like the middle ring would help with that.

Went out for a short ride yesterday and Gill says  with the 48T ring on the pedals are turning slower than she would like.
I'll have another go with fitting the 44 tooth ring.

I don't have a problem with the Bafang ring - a little agricultural perhaps but not poorly made.
The plastic chain guard however ....

Just had a chat with Brighton eBikes.  Lekkie have a 40 tooth dished ring which will fit with the BBS01/02 when the reduction gear casing is replaced with a smaller version - I'll wait and see how much that costs before making a decision.

The 36 tooth is not dished and would result in a harsh chain line on the bigger sprockets.

Apologies re the lengthy delay in updating this saga ... but the end result is a success  :)

The original/standard 48 tooth Bafang chainwheel was too large for Gill to make much use of the rear sprocket cluster - she was mostly cycling on the largest two sprockets.  We did try a Bafang 44 tooth but this would not fit with the 9 speed Shimano chain - which worked fine with the 48.  Personally - I think the 44 tooth wheel was either cut from thicker steel or had too much paint applied.  So I got in touch with Brighton eBikes and we have ended up with a Lekkie Bling Ring 42 tooth as this will fit onto the motor unit without modifications. There is a 40 tooth version but that come with a replacement outer cover for the motor unit gear casing - as you might imagine - costs a lot more.

With the new ring fitted we went off on holiday to Scotland (motorhome touring) and had a few days out on the bikes.  For us, this is a success as Gill is now not feeling like she has to struggle to keep up and I'm not either worrying she is not enjoying the route or stopping to let her catch up.  We did a route along the Solway coast to Caerlaverock Castle and the Wetlands reserve on a greyish breezy day.  On the way out she had the assistance set on 2 or 3 and we were able to talk comfortably as we went along.  As time went by and the breeze picked up, she wound the assistance up and finished the day on 6 or 7.  Into a headwind for the last 10 or so km we arrived back both in about the same state of tiredness.

I did make up an aluminium adaptor for the battery box to allow it to fit onto the Thorn bottle lugs, but aside from that the fitting went pretty much straightforward.

Worth watching videos of the fitting process if you want to have a go - its not difficult but the supplied instructions are not good.  I found this Rev Bekka video easy to follow. 
https://www.youtube.com/watch?v=rcYVyuDC6e8 (https://www.youtube.com/watch?v=rcYVyuDC6e8)

Very impressed with the assistance from Brighton eBikes too - If I convert one of my own bikes I'll probably buy the kit from them.

photos to follow - possibly when I have tidied up the wiring and battery box adaptor :-)

Thanks to all for your advice etc.
