Can't Fault


  (United Kingdom)


5 5

The bike came today, 15 minute set up. Used the Allen keys the came but the end came of in the bolt so it took me 10 minutes to get it out. Excellent bike, works fantastically. The bike to me is worth every penny and more. The only thing I could complain is the delivery time but that isn't anyone's fault but DHL.

Great Value for Money

For the money you can't fault it

Ride position is spot on for me

used for 2 to 8 weeks For the money you can't fault this bike you really can't. Yes people say it's terrible but that's when you expect the same suspension performance as a £4k bike I've ridden worse bikes costing £700+

I'm a big guy. to be honest too big for the spring on the rear (I knew this on buying and am fitting an air shock) when riding a old roman road I can sit down and put the power down on my hard tail I have to stand up and carefully weave through the rocks

My only gripe is the wheels have a lot of sideways flex but come on a decent wheel set can cost you the same as the bike

If you want a bike for general pottering about off road you can't go wrong and if your like me and you plan up building it up as a project you wil have a very good bike
