Q: What sort of a job will I have installing the kit on my push bike?

First of all - Beware of comments posted around the net saying that installing your bike kit should never be left to the average person.  THIS IS absolute rubbish !
Any practical-minded person will have absolutely no problems doing so...  We have all the necessary support material on site which you have access to after your order has been shipped.  There's a step by step document showing what do do with written descriptions and photos.
The only difficult thing WOULD BE, if you had to spoke your motor into your own wheel, WHICH IS WHY we have gone to the trouble and extra expense (shipping primarily) of PROVIDING A MOTORE ALREADY SPOKED INTO A NEW WHEEL complete with tire !
