    Brushed EVT trike

    Got it working with the motors in series. So maximum 15/20 m/k ph. But mostly going to be used for cruising round a field looking at cows anyway. Found that the rear brakes stick a bit. Which I only noticed when the battery charge diminished rather rapidly. Next stage build/find/liberate a...

    Brushed EVT trike

    I didn't even think about running them in series but that might not be a bad idea. I've forgotten the model of the curtis but its way way overspec for the application at hand. It must have been in someones parts bin from a forklift. I'll see if I can find a photo I should have taken of the spec...

    Lead acid anyone?

    Am using lead but not for a vehicle. Well the pack came from a vehicle originally but a 1000ah 24v pack is a bit big for my push bike. Been merryily powering my folks offgrid home for many years now.

    Small water cooling pump test

    A lot of R&D for watercooling electronics has been done by the PC over clocking community. It might be worth seeing what you can cannibalise from their efforts!

    ebike motor > to > wind turbine conversion?

    warning, mega old thread revival. Just posting for completion for other future searchers. schottky diode's are what you're looking for. Very high rated and low voltage drop. Tread mill motors are okay but vary wildly. The best way to tell is to divide the max RPM by the number of volts, as...

    Advice on first RC bike project?

    Thanks for the advice, I will probably end up lurking for another six months before trying to build anything! I'm in Nottingham or there abouts. I'm tempted by the RC route because time and a little manufacturing skill I have, money? not so much... Do you mean like this? I will start saving my...

    Advice on first RC bike project?

    You sound to be in pretty much exactly the same boat as me, except I am more interested in a mid mount chain drive solution. The joy of RC type motors is they are a cheap money investment, on the other hand they are a massive time investment since you need to fabricate a two stage reduction...
