Good Budget Pick

My son keeps telling me how smooth it rides and how much he likes the gears. At this price, getting real shock absorption plus a derailleur feels like a steal.

Looks Really Cool

Haven't taken it out for a proper test ride yet, but assembly went pretty smoothly. It matches exactly what my kid wanted, and that black color looks awesome.

Hill?Ride Difference

Super happy we picked this 21?speed model. It handles uphill climbs far better than our old single?speed bike.
