About Us

Since 2000 we have been working on electric bike conversion kits for bikes of all shapes and sizes.

In the past year we have concentrated on a vastly improved nano conversions for Bromptons and a selection of other bikes with a more compact wiring harness, slicker motor components and moving the controller off the handlebars but keeping our trademark 'ONE CLICK' system connection via the front luggage block. 

We now have workshops in Leamington Spa and Marlborough and a growing networks of engineers who can provide fitting services around the UK and Europe.

We live on a steep hill, a mile up from the shops and a quick pop down for a loaf is no longer to be feared, or planned well in advance.  Anthony

It is the best thing I have ever bought, saves me at least ½ hour a day on my commute and means I am independent of public transport if I need to be. Geoff

I love my nano electric brompton, there is no way I would have even considered cycling without the electric boost. It makes up for the pony I didn't get when I was twelve! Karen

"I am so impressed with the elegant connection with the battery in the Brompton bag connecting to the front block, it is so much better than the alternatives which seem so clunky by comparison" Ian


Use your nano battery to power front and rear LED 
lights on your Brompton. 

Easy retro fit to the nano conversion 

Nothing in the lighting package affects the fold. 

£55 for the front light only, if you already have dynamo lights or £100 for the whole package.

Compact battery bags

A new addition  to our bag range is the waterproof Ortleib Compact bag which can be fitted straight onto a Brompton luggage rack or attached to the handlebars or handlebar stem of other bikes with special fixings.

The Bosch or Oregon 4Ah batteries fit nicely inside.

4Ah battery options

We have been selling the Bosch 4Ah battery for some years and are delighted to now introduce an Oregon 4Ah battery to our range.  

This battery can fit into a Brompton bag pocket or into the new compact bag. 

The range is the same as Bosch from 8 - 16 miles on a single charge. 

2 of the 4Ah batteries can be taken on a passenger plane and at only just over 1kg each they are light, robust and flexible.
