After all the nightmares with my bike, now it's the charger that's dead. It's a 36 volt lead acid battery charger. It started by making weird buzzing sounds and working only when held at a specific angle, and then just gave out completely. Is there any way I could find and replace the...

As I was saying on another thread I needed a new transistor and diode for my bike controller after breaking the pins on 2 of them, and then after one transistor jammed on. I just soldered a new of each on my controller and cautiously turned my bike's ignition key while holding the power wheel...

Is there a way to wire a mosfet with no or minimal additional components (no computer like in regular controllers, at least mine has a motorola 8 mhz cpu with a few KB ram and 32 KB storage space for the software that controls everything on the bike). Can I simply wire one like a relay? What...

As I've been saying my bike battery was literally dead, it barely lasted 1 km. I was going to spend $500 US on an nimh 12 Ah and charger but for several reasons decided not to and to get 7 Ah lead batteries for $57 instead (yes, that's $57 total, of $19 each for three 12 volt, 7 ah batteries)...

To those who know electronics well, I need to buy 2 transistors but have no idea which I need. There are 2 transistors on my bike's controller which on the board are labeled T1 and D1 and the pins accidentaly broke off while mounting a heatsink, from a google search it seems T1 and D1 refers...

Since I doubt I'll ever get the pedal assist back on my bike, I need to start looking for new models or possibly even better bike upgrade kits so I can choose my own bike. Is there any kit to build your own ebike with a pedal sensor other than the $2000 bionx kit? Otherwise what pre built...

I noticed the excessive cost of the bionx kit seems to be mostly from the battery, it is far more expensive than any other of the same capacity, I could cost hundreds off the cost by using my own battery. So is it possible to buy all parts of the bionx kit individually except for the battery...

I noticed many people here have bikes with auto pedal assist. My controller blew and I'm dying to find one with this feature. How come so many people have this feature and many bikes are for sale with it, but no one sells any controllers with this feature. Otherwise, I at least need a 36v...

Ever since I got my ebike I've been getting flats nearly every 2 weeks (compared to 1 in 10 years with regular bikes), probably costs me more in tire repairs than it costs a xar driver in gas for the same mileage. Are all electric bikes like this? At the bike shop (didnt buy there, they're...

Well I got my new bike controller with no pedal assist feature, so I decided to plug the peal assist sensor cable into this new controller's throttle input. I try the bike and as long as I don't pedal the motor doesn't work, as it should be, when I pedal, the motor starts, as it should, but...

Firstly, I want to say I know exactly how a brushed motor works, what I don't understand is how it can possibly work which such high amperage. I've had an endless amount of heavy duty switches that can probably handle switching a kitchen stove on/off solder themselves into the "on" position...

As many of you have seen I'm desperately looking for a bike controller with pedal assist, but it seems these controllers no longer exist, yet I think some bikes are still being sold with this feature, so how is this possible? Am I stuck with a "manual ebike" forever? I loved the automatic...

As I've been saying in my posts my bike's controller blew and it's battery has abou 25% it's original capacity, so it's barely an electric bike at all anymore (I replaced the controller with a simple relay circuit to at least have on/off capabilities). Since I can't find a new controller with...

If I'm unable to find a new controller for my bike, I'll sell it as is and probably get the Strong GT-S210 but I have some questions. 1. Does it come with lead acid or nimh batteries? 2. Does it have a pedal assist feature where you pedal and the motor will automatically kick in to assist...

I got an e bike last year from Novawheels Electric Assist Bicycles, the Nova-I model, but the computer/controller recently blew, the company seems to have gone bankrupt. I asked in another thread about where I could get a replacement controller with pedal assist feature and got no reply. I found...

My controller on my bike somehow blew and I got another on ebay for $10 but it was just the motherboard with no cooling case, so without proper cooling it overheated in 2 days of use. So I'm again looking for a new 36V, brushed controller with an input port for an automatic pedal assist...
