    How to add a BMS to lipo batteries?

    If you can avoid lipo, I'm advising to avoid to get them. I've been using many lipo pack, and I'm still using my last lipo pack. But they are designed for RC and not for ebike. So your pack will suffer many inherent issues: - Many potential points of failure: HK is not famous for its lipo...

    These are the dropout washer from BMSBattery: These are made of soft steel, maybe mid steel. They break in 2 really easily. Better not having them.

    I damn D8veh, you should have posted a review. That would have avoided me to buy these cheap torque arms :( I'm thinking to get the "best in class" torque arms from Dr. Bass: The axle is 14mm wide right?

    Dahon Jetstream conversion

    I realized the normal commercial dropout are definitely not enough with my bike torque. Left torque arm: Right torque arm: I have these 2 torque arms strongly attached... and I realise that the axle was widening through the 2 torque arm holes?? :( Damn it's only 2.8KW... I need stronger...

    Carry a passenger on my bike

    Today I carried back a friend to the train station on my Dahon jetstream: It was like that: (of course, the one behind was a WOMAN and not a dude like the picture) For some reason, it rode surprisingly well. WAY BETTER than with the bikeseat I purchased for £150. Handling was quite easy. I...

    Who likes Crank-drives?

    My dahon jetstream could potentially fully rotate. But my wiring didn't allow me to do that. When I say wiring it's not just the controller wiring, it's also for the brakes and gear cables. So I just show you the "potential": We could potentially have a quick release to allow rotation like...

    Who likes Crank-drives?

    My thought is that the simplest way to get started is to use a second hand mezzo bike: And find a way to do the following: - Add 20" wheel - Add front suspension - Add disc brake Frame coud be updated to add 20kg batteries :D

    Dahon Jetstream conversion

    Yeah that looks complicated. I don't know anyone able to do that... If I knew, I'd have already modded my bike several times lol. Can't your friend who does welding help you on this part? If you manage to find any way to sort that out, count on me to buy a bike :)

    Dahon Jetstream conversion

    BMW has such a bike: http://www.foldingcyclist.com/BMW-folding-bike.html But it seems that the bike is overpriced and not sold anymore... Maybe another way to solve the problem is to get a Mezzo bike and extend the rear to allow bigger wheels. Then mod it to add front suspension.

    Is this your stolen Oxygen?

    My guess is that he's just going to ignore you. Or insult you. You can't accuse anyone without proof. He knows that. I can't count the number of scam I've seen online with guys lying until they found out they're spotted. Then they'll ignore you. Not a good way to catch the guy

    Is this your stolen Oxygen?

    Does smell a bit like a stolen bike. Seller is new too. A lot of risk is taken by being ebay seller as it needs bank card and address. It's when you start to ask for the serial number that the seller disappear.
