Hello

[James Dawson]

In the process of building an E-BMX. The frame was an old battered silverfox (Cheap Argos thing) But its all Aluminium so its ideal to save on weight! This will be used off road and I'm fitting a 1000w hub motor in the front wheel.

Just waiting on parts now, should be complete in the next few weeks! Really looking forward to trying the thing

1000watt front motors and alloy forks. Not a good combination. I have never done it but some experts here can advise you. But think front wheel departing forks at speed. Then forks hitting ground followed by your teeth.
Get some advice please.

The front forks are steel, should have mentioned that. There actually SE landing gear and are considered the strongest reinforced forks for a BMX. The headset has also been sleeved and welded up as it previously included an internal Gyro. This is also ridiculously strong now and highly unlikely to break.

id not try to even go more than 30mph on that as you might find it start wobbling over that speed.

also you will need disc brakes.

I'm leaving the original V break on the rear however I will be putting some big sticky pads on. I will have a disk on the front with a hydraulic caliper. I don't expect it will do more than 30mph due to the 20" wheels. Not that I would want to anyway.

Interesting project. Good luck and keep us posted on your progress please James.

If it's not too late, a motorised back wheel will be much better. A front one will upset the steering and you'll have problems with traction. Small 250w motors are OK in the front, but you shouldn't really go much more than that.Why did you choose a front one?

The rear frame is incredibly narrow, we did think of widening it but it would have been alot of work. I'm mounting that battery on the rear so hopefully it will be a little more balanced with the motor on the front. I have considered a motorbike steering damper to try and make it less prone to torque steer. If it doesn't work out I can always just put the front motorised wheel on the rear and remove the crankset. I'd just put motorbike foot pegs on. As its for off road use I cannot see it being an issue until the battery dies when I'm miles away from home lol
