For many advocates of electric bicycles the preferred way of delivering the power of the electric motor is so it goes through the gears in the same manner as the riders own effort. To make this type of assistance possible means having the motor installed at the crank (where the front chain ring is) or between the front chain ring and the rear wheel (attached to the chain).

Until very recently the only way to have this type of motor fitted onto an existing (non electric) bicycle was by putting it between the front chain ring and the rear wheel – a reasonably efficient method, but not always easy to install and set-up, and to many eyes a rather inelegant solution, but all the same an effective method of electric assistance – see some examples here:

However, now a new product is available which can be installed on an ordinary non-electric bicycle (your own favourite maybe) and give the same level and manner of assistance as the excellent but expensive electric bikes built around the Bosch or the Panasonic Electric Motors – for example.

The Mojo is a light, quiet and powerful system that adds electric assistance to any bicycle

The new motor aptly named The Mojo is being marketed by a long term exponent and developer of electric bikes, Tony Castles, under his Mr Motorvator trade mark. The Mojo system is installed by removing the existing cranks and front chain ring on the donor bicycle and then replacing with the Mojo. Something any reasonably competent cycle mechanic could do, and well within the abilities of many a DIY-er. See more here:

I must say having coming across this motor only a few days ago I am still slightly (and apologies) drooling over it – in short, I want one!

Having had dealings with Tony Castles before (and aware of the great enjoyment the Nano drive electric conversion kit for Brompton Folding Bikes, that Tony developed, has brought: I’m sure that any product he shows his confidence in, by selling, is likely to be a good’un. And for product support – well it’s good to deal with someone who really understands the technology.

If I give in to my urge to get one of these Mojo drives (and resistance is not necessarily futile, but at least rather difficult) I’ll do a write up of my on road experiences using it.
