The rain on Tuesday got into my charger and it's dead! It was a Sans Electronics 42v at 1.8a - I have tried 8fun (now called eccomobile) but they have no old stock. Any ideas on how to source a suitable replacement? The DC plug / socket looks like a TV ariel - anybody know what that is called...

Browsing DX I found this:- Replacement 22.2V 25C 3300mAh Lithium Battery Pack for R/C Helicopter - Free Shipping - DealExtreme It's described as a 22.2V 25C 3300mAh Lithium Battery Pack but I'm still very shaky on Ah and mAh - how many of these would I need to make a 44V pack with a reasonable...

This is a about a pedelec but is more a general cycle question. I have now been through 6 different inner tubes and two tyres - I cannot manage more than two return journeys without a rear flat! :( I am 18 stone and riding a Dawes hybrid with a Sunlova kit that places the battery over the...

Would this:- 36V 350W brushless controller for E - bike & scooter - eBay (item 300371271592 end time Nov-21-10 05:49:19 PST) make a good replacement for the 15amp controller that came with my Sunlova kit - I'm hoping to trade range for speed. The illustrated connectors look fairly similar...

I recently came off my bike (and broke a wrist) and one of the reasons was a lack of brake power. I have a converted Dawes and it has disc fitments on the rear but a non disc rear wheel. The front conversely has my 8 fun hub motor with disc fittings but a standard fork without calliper...

As promised here is an account of fitting the Sunlova kit - 1st thing I should say is I am very pleased - it wasn't completely trouble free but it works and didn't take me too long :) This is what I got:- I'm quite pleased with the overall look - I'm particularly pleased with my...

My Saturday purchase turned up today - a day early. 1st impressions are very good - the wheel and hub look great and I note the hub has the fittings for a brake disc. Battery and carrier look like many of those I have seen on here - the controller is pre wired and everything arrived...

I understand how a controller can manage voltage and amps to control power (under my school friend Ivy Watts :) ) but how can the controller limit 'speed' ? Unless the controller knows how many RPM the motor is doing and also knows the diameter of the wheel it is fitted to - but this seems...

What happens if you have a 48v motor and you run it on a 36v battery? I ask because I'm considering a 48v Lead acid install BUT i would like to convert to a Li ion battery or LiPo later. :D

Forgive me - I am new to these and I have nver ridden an electric bike! I'm going to buy an Alien Kit (I think) - I have a hybrid and a cheapish montain bike as donors so I can't really justify a whole bike. Q1) I'm veering towards the Hybrid (700c wheels) for my conversion - is this wise...
