Looks like a lot of fun. But as a cyclist and motorbiker, gotta say ebikes need regulations. Bike trails shared with pedestrians and cycles aren't designed for high speed. The rider and other users need TIME to react. At higher speeds, you have much reduced time. And there will be an increased 'freeze' by the other user who doesn't recognise the new threat and isn't able to assess the safe thing to do. They are also much quieter and have a narrower profile than motorbikes which warns other road users by noise and visibility. Looks like little or no ppe like helmets or armour. Hitting a kid on a trail, path or road at speed will kill or seriously injure. Could you live with that? For a bit a fun that you can have using a regular bike or registered electric motorbike?

Funny you should upload this now as I'm about to build my first ebike. I've been wanting to get a cheap chinese dirt bike for a few years as I don't mind tinkering and it fits the budget, but seeing as how I love tech and probably won't be able to afford a Tesla for awhile, an electric offroad machine should suffice in the meantime. Aiming for 52-72v, 1500-3000w but still working out specifics. Thinking about integrating it into some sort of 20 Fat Tire BMX/Mountain bike hybrid. I'd go balls to the wall and pick up a Zero dirt bike but most everything I want prebuilt is out of budget, and so I resort to lower spec and DIY, just like on PC; )

yall are awesome for warning everyone to ride responsibly and within your capabilities. Im from Singapore and we were the most advanced electric bike and scooter country in the world till our government essentially banned electric scooters. mainly because a 16 year old boy killed a 60 year old lady. Please please ride responsibly guys so everyone can keep riding, it only takes afew accidents for all ebikes and escooters to be banned. here is Singapore we used to have 120v systems with dual motors, and dual 120A controllers ridiculous power. But now we have nothing and our vehicles are being confiscated by the government.

Long time ebike builder here. The best advice for building high performance ebikes is your battery cell selection. The high current controllers require a lot of power. If you get too much voltage drop you will kill your battery lifespan very quickly. Also, a 'lower capacity higher discharge 2. 9/3ah' cell will actually have a higher overall capacity compared to a 'high capacity 3. 4ah' cell when put under significant load as the 'high capacity' cells are only rated at that capacity at about 1 amp or less.

Still, at 1500 for that battery, it would only have to last about 4-6 months to pay for itself in fuel offset (least for me) of travel to/from work. Sadly it was 40km one way to work for me back then, so it wouldn't work for longer commutes, but living in a city it would easily pay for itself. I'm just estimating, but the time spent idling in traffic in a larger city would easily eat up as much fuel, I imagine you're burning about as much gas as open highway travel over a longer distance roughly.

If you DIY these things they are so nice, fast and perfect for the city also not even that expensive but Germany is hell for DIY, anything that goes faster than 25kph you need a registration for and guess what, to get one the manufacturer has to register the thing in Germany as a model type but if your the manufacturer the only way to get registration is through a special individual permit which is around 5000 for two wheeled vehicles. It's similar in the rest of the EU.

Shunt mods are easy with solder, just make sure you watch the amps externally. Also, while you're in there you can check out the transistors and caps to get an idea of what kind of juice you can push through the box. Also, you can Google the transistors and find out what it will cost to replace them if you pop them. I've been playing with the fat tire scooter controllers trying to push them to the max before stepping up to something like this. Great video!

These bikes make no practical sense. With the amount of cost involved you can literally buy a dirt bike with far greater range and performance in every single metric. They're just an excuse to ride dangerously fast on pedestrian paths. The PSA is useless, It's only a matter of time before laws are passed for the safety of the public. Just like with what happened to the idiots that abused hobbyist drones and are now facing FAA regulation.

i ride a honda 450x sumo. as people are walking around the (suburban) neighborhood more these days, with kids and dogs, I find I am having the same kind of DBaD (Dont Be a Dick) awareness, not hitting the throttle as I pass them, giving them room, being aware that they are afraid/annoyed of the noise and motion, so as to keep them from calling the cops, and so they dont get all pissed at every bike they see.

Is there a way to set up passive regenerative braking? Not sure if that's the best way to describe it. Like, with a tesla if you let off the accelerator it'll start to regen some. And if you completely lift your foot off it'll try to completely stop you electrically. They do some software magic to make it less jarring. It'd be cool to do something similar with e-bikes.
