I would have given this product five stars had it not arrived without any printed assembly instructions. As I had a good set of tools and some mechanical experience I was able, by deduction, to work out what should go where. Someone without either would find it a struggle. As it is, the bike is excellent value for money; the build quality top notch, and the performance brilliant. My first ride after charging the battery overnight was a round trip of 7 miles, plus an evening run of 3 miles to test the lights. The ten mile total had reduced the battery level to three reds - four when fully charged - so there was ample in hand for use next day. On the debit side, the bike is fairly heavy, but perhaps they all are. A plus in this respect is the foot-operated retractable stand, which is an absolute boon when when parking. All in all, a very handy addition to my personal campaign to cut down on the cost of petrol and CO2 emission. Alan
