## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent value for money
*by S***N on 29 March 2025*

Better and bigger than I've expected and excellent condition. My daughter loves it. The mudguards are of low quality ,but the bike is beyond expectations and very easy to assemble.

### ⭐⭐⭐⭐⭐ If you’re are not good at assembling you may need an expert to arrange.
*by A***A on 10 September 2025*

Good cycle- value for money and has got a cool look

### ⭐ Failures after only a couple of rides
*by B***N on 7 September 2025*

Really disappointed, I managed to use the bike maybe twice before the gear system just completely stopped working. Permanently stuck in 1st on the left side gear shift, no amount of tinkering, without making the coverage void will fix it; just cheap parts that fail. I'm hoping the seller will do the right thing and provide a refund. Update: the seller contacted me and asked for photo evidence, totally understandable, and I provide said evidence. They then agreed to send me a replacement bike. However, since then, I’ve heard nothing, no update, no asking for my address, and they’ve completely blanked me. No replacement bike, no refund. These guys are completely unreliable.
