Used for 2 to 8 weeks
very good designed for kids
Poor quality of paint
Used for 2 to 8 weeks
This bike is a nice one, I took it for my daughter the girl one, but the lower part of spokes have started to rust in just 2 months and paint of the body is also not satisfying me. Should have chain guard as it is for kids.
No safety for beginners
Used for 2 to 8 weeks
This BTWIN racing boy 300 is good overall.but steering has 180 degree rotation which is absolutely not safety for learning son fell down two times due to this.there should be 90 degree angle limiter in this bike.after learning we can remove this angle limiter if we want.I recommend to add an accessory(the steering angle limiter for 90degree) which is optional to buy.this is important.
Good bike can be a little more cheaper
