Re: E-bikes: depressing or what?

E bikes would catch on if we were a cycling nation like the Dutch, how ever in the whole we are not. Most only have a bike for recreational use for the odd weekend ride out in nice sunny weather. A lot of non bikers, who or if they buy one will use it infrequently and in the long run the battery wil...

Re: Converting using a e-front wheel.

hemo, that's the best bit of advice for me 'cos I'm over 100kg. Excellent. Where can I get one? The Bafang website seem to be a trade only supplier. Have a look at Woosh bikes kits (Southend). http://wooshbikes.co.uk/?hubkits Or China sellers BMS Battery, Elifebike.com and Greenbike kit.com. Ideall...

Re: What's best for a hilly area?

Another question, about crank drives: may have tiny chainwheels, so what are they like to pedal if either (heaven forbid) you run out of battery, or turn it off to conserve it e.g. on a long run? Are you left turning a ludicrously low gear, or does the drive go through and internal gear train with ...

Re: What's best for a hilly area?

Bafang bpm or SWXO2 hubs are awesome and very powerful an equal to any mid drive on the road for hill climbing look for a 201 -250 rpm speed motor rating. A cadence/pas sensor makes for a nicer ride esp if your legs get tired as it only requires a gentle pedal rotation to kick in to whoosh you alon...

Re: Taken the plunge.

The wattage rating is defined by the copper motor windings. Drive units to have 250w continuous rating without over heating. UNECE regulation No85 defines that said motor will have a higher wattage output however the output must only have a max 30 min duration. Obviously a 250w rated drive would sta...

Re: Taken the plunge.

What an interesting thread - I'm a theoretical fan of ebikes (in that as yet I'm not considering getting one but the knees are starting to tell a different story :shock: ) - hopefully before I do need one, the situation of power vs legal limits etc will be more settled. Youtube and searching 'bafan...

1+ for the Weldtite strip cheap at a few £££'s on ebay and works without fail all the time, cut it in to sizes to suit your needs.

Re: Circe tandem pedelec conversion kit.

Always willing to give helpful advice, as with all conversions effort and time has gone in and a shame for it to fail for a simple install error. BTW conversion looks really neat and proper, nice work.

Re: Taken the plunge.

Although my first post here have to agree with Eddie. There are only 2 legal BBS's both 01 or 01B versions they are factory stamped as 36 250w 15a or 36v 250w 25a. The factory settings/parameters are usually set to be very tame mainly to prevent controller issues and warranty claims, to get the bes...

Re: E-bikes: depressing or what?

Depressing why ? People have got legs they can walk but choose to use polluting cars, rather then bus or train. The use of ebike has now cut my car use down to under 1k miles a year now. We all have some sort of central heating but before the 70's was a rare commodity most relied on an open fire or ...

Re: Converting using a e-front wheel.

Depending on how heavy you are ( 90/100kg or more ) then you will ideally need a high torque Bafang bpm hub, these are 4.4kg 180mm quite heavy hubs on a front wheel. They do produce some wheel spin on loose or slippery surfaces but nothing to bad, they excel at hill climbing. the 201rpm code 13 bpm ...

Re: What happens above 15.5mph?

Above 15.5mph you go faster :D . All my bikes have China kits on them bar one which is an s - pedelec. All the China kits can be manipulated to ride with assistance above the cut off, as long as you pedal well and hard no one is bothered. The only time you will get noticed is if you use a throttle w...

Re: Electric Bike Conversion

Roadies are the hardest to even speak to when change comes along, they don't accept that other riders have differing needs or requirements. In their eyes if you don't sweat or go red in the face at the point of bursting a vessel then you are not cycling, no pain no gain. Ebikes can allow for a gentl...

Re: Q: How much resistance when motor is OFF

My error didn't read the post correctly.
My bbs01 is similar when unpowered the slight resistance is probably down to the internal gearing, though like a hub you are still riding a bike that is heavier and weighs about the same with a battery as well.

Re: e bikes and effort

Twist and go is legal though you need to pedal to activate it whilst riding, other wise they are only meant to 4mph /6kmh walk assist mode when not pedalling.
Saying that 4 of my ebikes are all configured via the set up menus for max throttle op at all times.
