Great ride

Pretty much everything.

The front suspension is weak but good for the cost

used for 1 week or less It's a great commuting bike and nice to ride along the canals, but I wouldn't recommend taking it on any rough trails or black routes. For the price it's strong and a very nice ride, top marks from me, not to mention I also got it £90 cheaper so that's always a bonus.

Good buy

used for More than 1 year I bought one of these bikes last year in January and it was amazing the day I got it and still is. I ride it daily around 10 miles a day. I am a big guy, I was 24 stone in weight when I started riding, im now 4 stone lghter and this thing stood up to the challenge except the bike seat , I did invest in a better bike seat as the other bent a bit, but that is probably because of the sheer weight it was handling! The bike was set up perfectly out of the box and its incredibly good quality. Wheels and breaks all fine still and excellently fluid still. I cant think of anything against this bike - seriously buy one as soon as you can.
