We have always been about power and freedom.  We all remember the first time we went off on our bike whizzing down the hill, peddling like mad to get up the other side, not a care in the world with a grin from ear to ear.

The only difference is, the spirit is there but age has taken its toll, so that bike is exiled to the shed or the garage along with the good intentions.

We have brought the grin back to cycling, putting the joy back into riding, making that dread go away.

We are always reviewing the market place, monitoring new technology as it comes to market.  We have been converting bikes to electric now for 15 years improving and evolving, never standing still.

After extensive research Motors, Controllers & Displays that meet our exacting criteria are then purchased to evaluate.  These samples are put through our exacting test programs for months to make sure they are reliable and robust before they are added to proven range of exceptional electric bike conversions kits.

We have never been in the market of box shifting.  This would go against the grain. 
Buying from us means you are buying a product with support.  We are to able to do this because we design and engineer the product ourselves.  We understand it.  15 years of trading and positive feedback proves this!
