    Rated 5 out of 5 by from wheelies I needed a bike that was light for wheelies, when this was purchased I could wheelie 2 days, 3 months later I can no hander and have added spokes lights and a SE Bike seat. thanks for a brilliant purchase and if this bike breaks ill sure be getting a new one since these are excellent.

    Rated 4 out of 5 by from Love the bike The bike itself was good and the bike was made up in time with no delays. I was not impressed with the fact that both front and back inner tubes had slow punctures!! This meant we had a sad little boy on Christmas day wondering why Santa would send him a bike with flat tyres! When we went back to the shop to ask for new inner tubes we were offered a puncture repair kit TO BUY!!!! Needless to say we told them we would be leaving the bikes to have new inner tubes to be fitted. The man who served us was not happy about this but they were swapped.

    Rated 5 out of 5 by from Much lighter than steel framed bike The light ally frame helps reduce the weight which makes a big difference for young kids. Standard of equipment is very good.

    Rated 5 out of 5 by from Excelent Bike Our son tried several bike and chose this one as it felt right. It is very well made and most of all very light. The colours are beautiful and all in all we are thrilled with the purchase.
