MOT – For Safety of Electric Bikes Only

If it’s that time of year when many of us are retrieving our bikes from the garage or shed, and realising that they’re going to need some attention before being ridden again. Where a long winter of neglect, cold weather and damp conditions has played havoc with the cables, the tyres, chain, battery and charger.

Then it's time to arrange for your electric bike to have a full MOT by us:

This e-mail address is being protected from spambots. You need JavaScript enabled to view it.

We check to see if there are signs of rust & there are curious noises when you turn the crank.
The charge for a full MOT is only £75.00 in many cases including parts and VAT!!!
This can be carried out at our own workshop by our qualified engineers.

Not only will you know if your electric bike is safe to use on the public roads, also if your electric bike is economically worth repairing and if you are better off replacing with a new electric bike, saving you time and money, take a look at our offers on our web site.

Battery Performance

A 10A battery should yield around 30 miles with some pedalling or 15 miles if you just use the throttle alone (not advised)

A 15A battery should yield around 45 to 60 miles with some pedalling and around 25 to 30 miles if you just use the throttle alone (not advised)
