I bought this for my 23 year old brother as a birthday present, put 85% of it together myself, the adjusting of the gears had me baffled despite watching the instruction video about 10 times haha but he managed to adjust them himself.
He's had it a week, drives it everyday, and so far its been perfect.
Has to take it to the garage to get the wheels properly pumped as unlike smaller sized wheels a standard bicycle pump just isn't strong enough and the air was just seeping out, however once pumped with a pressure pump at our local garage they've been perfect ever since :D
Delighted with it!
Ps. The local mechanic said he couldn't believe the price of the bike, he said to buy it here in Ireland it would cost over 200 euro!
