It's a ~$50 Gumtree special 2nd hand steel-framed mountain bike, with ~$150 worth of AliExpress Chinese electric bike conversion parts, and a ~$60 battery (You'd need another ~$50 for a charger - I use one of my quadcopter lipo chargers. That battery was originally a big quad one too, so my total outlay was only ~$200.) It gets ~25km on a charge with no pedalling at all (I use it for my ~16km round trip commute and it rarely uses more than 50% of it's capacity, even when I consciously avoid pedalling...) It's _technically_ illegal - it'll put out ~450W going uphill when fresh off the charger, and it's configured with a twist throttle like a motorcycle. To be street legal it'd need to be limited to 200W with the throttle, or 250W as a "pedalo" (where the pedals need to be turning to activate the motor). I've left the controller settings to top it out at 25kmh though (it'll do over 40 if I remove the software limit), so it's not tempting me into going so fast it'll attract attention from the cops... So long as my legs are moving enough when they see me I don't behave in an illegal fashion...
