[trikes] Power assist for Anura

[Ian Sims]

No problem fitting a hub motor to the front.

See. www.greenspeed.com.au/Anura.power.side.1200.jpg 

You just need to choose a front motor with a disc brake mount.

This is a Bafang motor, see :-

I did not encounter any traction problems, and AFAIK the customer
has been quite happy with the conversion.

Don't leave us hanging Ian.   Which is it, the Orange or the Apple?

My GTR is orange, please say orange!

Has anyone tried an Anura with a front hub motor yet?  Can it be done 
with 16" wheels?  I would assume the Anura might do better than the Kett 
with the rider position being further forward (on slippery roads anyway).
