Surely this isn't street legal?

48 volt (4x12 volt lead acid batteries) 2 x 1200watt giving 2400 watts of power = A very quick electric bike. 45- 50mph is easily achieved on the flat. It has the potential of reaching 70mph downhill (recomend a tail wind and brain disconnected). Oh and it will wheelie. I bought a kit and thought it would just bolt on. How wrong I was It has taken near on two years and a lot of expense to develop and finally get it sorted.

Ben at Kinetics has a good guide to legality on his site

In summary:

• 200W, 15mph, with pedal sensor: Completely legal to use on UK roads (and European, for that matter). Legal for the manufacturer to supply without a type approval certificate.
• 200W, 15mph, without pedal sensor: Completely legal to use on UK roads (but not European). The manufacturer should supply a type approval certificate.
• 250W, 15mph, with pedal sensor: Only legal on tricycles and tandems in the UK, NOT bicycles - a bicycle can only be used on the road with a license plate, tax, insurance, moped helmet and moped license for the rider. The manufacturer does not need to supply a type approval certificate.
• 250W, 15mph, no pedal sensor: As above, but the manufacturer should supply a type approval certificate.
• Above these limits: As above.

Thought so.

It's on ebay, seller has been using it to commute, probably realised it's illegal hence selling it.

Would require DVLA registration, Insurance, MOT and Licence to ride legally. Doubt it would get an MOT anyway.
