>>1541240>It's not a great idea tbqh. If you're nodding to change a 25kph to a 45kph that's totally understandable.Depends on motor. Back in the day they were pretty powerful, and limited by controller, but now they seem to be would for 250W 25 km/h no fun edition.
> If you're taking a 45kph ebike past spec that comes with risks; 45 kph ebike is not ebike but a moped... So it would make more sense either build an ebike with "250W25KM/H" brand motor that does 80kph (which would be pretty hard to make semi-legal) or buy motorcycle.
>the motor should be fine will run a lot less efficiently past spec. Motor probably runs at same efficiency (unless it is would with aluminium shit), but real losses come from wind.
Before ebike I had an electric scooter, and it was obvious, go past 21 km/h, and you turned your nice 10w/km into 15-20w/km. Idk, but on scooter you really dont want to go above 40 km/h, this is really a death wish speed, because you have no brakes, no control, nothing. Speaking of no brakes, on e-scooter I hit a light pole at 20 km/h, so I guess dumb people never learn.
>The real danger is blowing your ESC or melting some wire insulation, or even a solder joint and causing a big shortThis is not dangerous, just frustrating.
Real danger is battery, because it has mean bastard lion cells which glow red hot when shorted. So BMS and battery fuses are important.
>It's not really worth it because you can only squeeze a little bit more speed out of a 36v power system anyway.By pushing 50V, you buy housefire hoverboard batteries, disasseble them, connect to proper 14S BMS and fuse, weld shit proper, etc.
>If need or want more power you kinda have to go the bafang route.You can push way more power in hub motor tho, since it is bigger. Bafang - I'd not push more than 750W there. But real benefit of bafang is that in case shit breaks, you have ability to pedal, while on hub motor it is kinda annoying, because it has a bit of drag
