Great teenage girls bike

The look!, easy gears, comfortable saddle

Heavy to put on bike rack


  (United Kingdom)

5 5

used for 7 to 12 months Great bike for my 12 year old girl (I know but teenagers start early!). Looks great and good quality parts for price. A little heavy for lifting onto bike rack is only downside.

Lasted less than a week

It's price

The seat collapsed, the bracket failed, gears bad!

used for 1 week or less I was tempted by the price of this bike, it seemed solid enough but sadly a known fault in the seat assembly caused the seat to tip backwards throwing the rider off. It was returned for a refund

Response of the brand

used for 1 week or less Hi
I have had this bike for about 2 weeks and only been cycling for 1. I was out on the bike this morning going to work and the saddle suddenly slipped from horizontal to 45 degrees and was extremely loose. I didn't have anything with me to tighten this so am not sure how loose it actually is. Any ideas on what the issue is ? and how easily this can be fixed and is this a common issue?

Response of the brand

I'm sorry to read that the saddle came loose.  It can be tightened using two spanners or adjustable spanners and is a relatively simple job.  If after tightening, the saddle still moves, we may need to send you a new one as a replacement.  If this is the case, please contact our Loyalty team who will be more than happy to help:

Mixed feelings about this bike

Generally a nice bike

Gears don't work


  (United Kingdom)

3 5

used for 1 week or less Bought the bike intending to use to get to/from work but the gears don't work properly (the do not select). Will be taking it back but now have no confidence that the bike is reliable enough for its intended purpose. When I return to the store, I may look at exchanging for a different bike as I have used my husbands Triban 5 and it seems to be a much better bike overall for what I need
