HAHA! Brilliant!
Its currently on max setting which I need to turn down before he has his first go later.
The bike is mint! Looks like it has never seen mud! (that will change!)
The rear end is very stiff - I think I'll strip it down and grease it all up - maybe even see if I can get some proper bearings for the axle (which I think I read on here is just a plastic sleeve rather than a true bearing)
The bike is quite noisey to push, but I think its mostly chain noise, and also some from the motor I think...its silent once it gets going, and similarly quiet when its under its own "steam".
The front brake is crap, and needs adjusting - but for now I'll leave it crap to save him going over the bars as he learns to stand up on it etc.
I had a right laught whizzing round the house on it last night, and up and around the drive. It is really really quiet and I'm so please with it!
I just hope the little dude likes it!
I'm thinking I'll let him get used to it, then in a few years when most people upgrade to a "normal" bike I'll switch it up to a 48v with custom controller, revised motor and lipo4's for power - but that can wait....
