Thank you for your help Cheers Alex

I just found great youtube which explain in details how to install a rear hub. This part explains how to widen the frame to allow 140mm hub into 135mm fork. Can this technique be applied to the following frame types? 1. 6061 Aluminium 2. 7075 Aluminium 3. Steel frame Thanks Alex

The description sais it is Electric Ladies Bike...

I keep hearing abiout this Sunlova guys. Their web site however appears to be dead for the last couple of weeks: "Directory Listing Denied This Virtual Directory does not allow contents to be listed." The Payment details page isn't very informative as well: "Sorry". Looks like...

Is it possible to fit a rear motor into your Marine Kentfield FS? I've marked both your model and the San Rafael as candidates for the conversion. So can it be done?

Number of spokes and the motor Is it possible to fit Bafang (or any other cheap) kits into rims with 32 spokes? For some reason, most of the available kits come with pre-assembled wheel with 36 spokes and I haven't seen them in 32 spokes wheels (except the nano kit in one of Cytronex bikes)...

Can you please proviide more details on "no real bms"? For example this battery has a PCB inside with all the monitoring and protection. However this battery has the same protection level and still shows the red-lettered warnings for using the fire-proof bags while charging. I am really...

OK, looks like the 44V option seems to be under the research. http://www.pedelecs.co.uk/forum/electric-bicycles/8265-my-lipo-trials.html#post103221 I would be glad to see what your findings are :).

Hmmm... They do have some nice batteries, however the disclaimer is scary: "When charging Battery Pack, please put battery in a fire proof container". Warnings for Using Batteries

How many charges had this cell survived before getting weak? Just an estimation would be ok. Thanks Alex

Great info, thanks for sharing!! I guess you will be required to use this charger to charge 22V cells, right? By the way, how do you charge your set of 18.5V batteries? Do you charge each one of these separately or do you use more than one charger to save the time? How long does it...

Hi Frank, Having an option to switch between the road-legal 250Wt to off-road-legal 1001bhp is cool! Too bad for me that your pricing model is off my limits. Cheers, Alex

That's an easy one :). I need the bike for mostly commuting/weekend rides. I know Cytronex would cover most of my requirements, except the cost, torque and the number of assistance levels. My requirements are: Have unassisted ( or with minimal assistence) rides on weekends. Minimal drag...

Additionally your front suspension may also do some nasty jumping under full power. I've seen this on cheap front wheel drive cars where too much power is pushed through low quality front suspension. Anyway, I've noticed your bikes has disk brakes. This may certanly limit availability of your...

Oh, just saw your reply. This is something I wasn't expecting... Frankly, I was ready to go all the way into building/ordering my own custom battery/chrger, but this "BMS" thing is still new to me :). I'll do some RTFM on the web, before asking silly questions about battery related technologies...

Thanks a lot for your reply. I am not sure what type of the controller would be better (and keep my bike closer to legal limits) - 36V/350Wt or 48V/250Wt or even 48/350? Thanks Alex

Hi, Which model is this Mongoose? I would prefer to stay within the legal onroad limits, so anything above 350 is not an option to me. I am also not sure if overvolting the 250W engine from 36V to 42V will keep the bike within the law, but, hey, I am going to use the slower engine to start...

Exactly. The Nano kit with more powerful and more expensive battery costs £665, so Cytronex will be targeting a niche market if their price would be higher than that. For the DYI maniacs, there would be almost no advantage to use either one of them when there are other Chinese kits with a...

Hi flecc, You are the forum veteran and I don't intend argue with facts you present. You obviously know much more than a newbie which I am. However if we talk about emotions, I just don't feel like paying circa £1000 for a rebranded Chinese kit when I can buy the similar...

Hi, I am very new both to cycling and to e-bikes. I am planning to built by own dream-bike and I've still got a lot to learn. Anyway, I understand that some cyclers use the 20" motors for 26" bikes to increase the maximal speed. Of course, the torque (and the hill climbing ability) is...
