This strongly resembles a gas minibike I built from scratch many years ago. I used plumbing pipe for a frame and it was rather heavy. I needed to register it because of the engine size I used. I had a lot of fun with it. It hadn't occurred to me to build an electric version until seeing this. Nice work. It's strange that individual states regulate gas engine sizes for scooters and bicycle conversions but don't regulate electric motor sizes at all. I wonder why you spent the extra money on a gasketed battery box when the cable entrances aren't sealed.

[@wildmanstudios6534]

That's actually NOT true at all. I live in Florida and every class of electric vehicle has a section of the law pertaining to it. The list includes: e-bike, stand-up e-scooters, e-mopeds, e-motorcycles, and yes electric cars that are also subject to laws.

That power output is enough to go about 65 miles per hour so gear the thing properly and get better mileage at the same speed and also more speed when you need it.

[@nothoughtsheadempty6220]

Needs a bigger battery to sustain those speeds. Power is no problem, but ~730 Wh is not enough to do anything other than a quick lap around a parking lot with that power.

[@C.D.J.Burton]

Either silicon seal the wires into their casings or use rubber grommets just to be safe. Perhaps add a tiny hole into the bottom of the case to free any condensation which might accumulate. But also, perhaps use a fire proof container for the battery, if it's lithium. I'm being extreme. The bike is epic in any case, inspiration!

[@DIYesk8Builders]

The ESC is probably the one part not to try and cut corners on. There are some cheaper ones out there, but they tend to break easily.

[@petevenuti7355]

@@DIYesk8Builders I agree, that's why I don't have one yet. And if it had regeneration ability and it didn't work right it could blow up the whole battery pack with me sitting on it! There's got to be some source for a motor controller that's at least possible to get. If it takes me a year to save up $100-$200 bucks, I know I ain't getting one for $20, and I'll never afford one in the thousands. I'm practically crippled and can't walk to town, the typical e-bike that that I can't even afford used won't get up my driveway, it's to steep, I got no driver's license, nobody to give me a ride, no nearby public transportation , and I'm not quite crippled enough for the insurance to give me a electric wheelchair...

[@coltonkirkman8714]

15/70 gear ratio for 7kw or 9.5hp and you only got 22mph??? You should be getting at least double. Try a 18/65. I have a built Briggs 5hp on a vintage mini bike with a 18/65 gear ratio it goes 65mph and it makes ~7200rpm. I usually use a formula to calculate top speed.(Rpm/ratio x Wheel D x 3.14 /12 /5280 x60) hope that helps.

[@DIYesk8Builders]

35 MPH top speed. motor is not nearing max power

[@Zevose]

Where did you get 22 mph from

Attached to a semi-auto electric start on an old 1970 Sears and Roebuck droper bird bike and it'll do 70 miles an hour all day but I'm rocking a 16 tooth drive sprocket on the engine, and a 23 tooth on the Wheel, and because of the small wheels only being 11 or 12 in, it's still way too much torque and I always take off in second gear. So I might bump up to a17t engine sprocket. But, I'll admit it's already terrifyingly fast, in addition to being on a small mini bike frame. At least it's 54 years old solid American steel. Probably safer than most newer vehicles lol.
