Good to see another UK vendor finally, somewhere cheaper than transformer cycles. Still though, me and you both know that the bikes are very illegal! But that still doesnt stop me and everybody else. Also one other thing I see you've copied and pasted that FAQ bit off of the transformer cycels websites, I would personalize it a little bit if I was you. A guy in America just set up the same business as you and copied and pasted a load of info from another vendor and he got into a lot of trouble! Just helping you out.
Also there is no UK vendors selling parts at reasonable prices, the only place you can get them is imported from china off of Yong Xing Machine Zone (where that video was from) or from America. The UK parts market is dominated by Transformer cycles who charge absolutely ridiculous prices for parts! He's charging 10 quid just for the clutch lever arm! Another example is the cheap plastic throttle and kill switch for 23 quid, I paid £1.99 for a better one on eBay. So if you could use a few kits to be broken up for spares and sell them at reasonable prices, even half the price of transformer cycles, you would still be making a profit on the kit itself, minus labour and heavy shipping charges. Just a thought, if I was you get in there!
