Yikes Chris I don't think I have seen a bruise that big before. I hope you recover soon :( Thanks for the reply. PS does that sound like I am saying your ass is big ? Regards Jerry

I am a big fan of DIY batteries primarily for the ease of repair as stated. Not for everyone but certainly have their advantages. If I needed a larger battery I would certainly consider Chris's method detailed above. Use of a BMS can cause more complications than not using one, but as he states...

I may just use the motor with an existing Tongxin controller and throttle assuming it is rated the same. Regards Jerry

Ha ha funny link. I loved the caravan :D Regards Jerry

Laroche I have just looked at the PDF that flecc hosted for me when I posted in the first few threads. It gives full details of the kit. The good news is it states that the regulator (they call it a "boosting rate regulator" lol) does control power from 0-100% so, looks like you will be able to...

It uses smooth steel roller bearing/gears. Check out this link for more internal pics. I wonder if the two year guarantee is genuine. Problem as always, is if they want you to return the motor back to China then postage each way would make it pointless. Regards Jerry

I have not used BMS, but someone was telling me that they have not been very good at turning round an order recently. Maybe its a one off and others find them very reliable. Regards Jerry

Hello Dan :D Nice to see you posting and thanks for the clarification. Regards Jerry

Laroche, When they say new controller I understood them to mean one specific for these new light/smaller motors. I have not ridden a bike with a pedelec sensor. As I understand as soon as you turn the crank the motor begins to cut in. Worth reading this. I am sure others will chip in, but I...

Laroche, Some one on here (I forget who) sourced those connectors for us to use on our current systems. Keyde just replied and told me the stepless 5 speed display does regulate pedelec assistance. Not sure if as you say low is "off". Unfortunately the smaller lighter v motor I have ordered...

I went for a 260RPM one for my 16"/20" wheels. I agree its hard to understand how it all connects up, though as I said my motor does not have an internal controller just a normal three phase power supply plug. As I am a thumb throttle junkie this is quite a departure for me, though I am hoping...

Cwah the motors varry in price depending which model you require. Costs where provided by Laroche a few posts back. At this stage I could not comment on overvolting the motor and don't intend to do this myself. I am more that happy with 15 MPH of assistance. Given that past experience with...

Spurned on by Laroche and after numerour emails with Sky Zhang at Keyde.com (actually they are same manufactures of Tongxins) I have also bitten the bullet and ordered one. Again I can confirm that their communication is excellent. I have ordered a 80mm V brake one which they do, but is not...

Not sure if you should leave it all night ? Maybe an hour or two and turn it off before you go to bed. Regards Jerry

My obligatory plug for a Brompton with a Tongxin motor setup :p Either buy one Direct or a DIY affair like mine. Regards Jerry

laroche Very interesting and thanks for the update. I had kinda given up after a few enquiries seemed to have produce little response. The motors are far from cheap, but I guess that comes with the fact they seem to be next generation in terms of stealth, size and weight. I would love to see...

On my Brompton I went from Marathon Plus to Kojaks and saved over 0.5kgs. The wheels seemed to roll much easier on the Kojaks, noticebly increasing my average speed by a couple of mph. One puncture in 12 months. The trick is to keep them well inflated and the Kevlar lining then does a pretty...

Not derailleur (this one has a two speed auto hub and is belt driven) but you can buy them fitted with them. Its sprung both ends! It uses a small Tongxin (2kg motor) plus a small DIY battery. Bike weighs 14.5kgs with motor, controller and tiny five mile 0.5kg battery. Its all in that little...

Maybe a kill switch would do the job. Small, waterproof and just hit it to kill power ...

Thanks guys. This bike does not really go out a lot in the wet so does not have to be quite as waterproof as my daily commute Brompton :) Regards Jerry
