TOP FIVE THINGS YOU NEED TO KNOW Our lightweight & durable aluminum Laser frame is easier to pedal than steel. The 20” Laser actually offers two types of brakes: a standard rear coaster brake, which most youngsters are familiar with, and a rear V-brake which many are not. Having the rear coaster brake as a back-up, allows youngsters to get used to hand-braking without going cold-turkey on the coaster brake they are comfortable with. Our alloy rims are anodized black to provide even greater corrosion and rust resistance than the alloy already possesses. Before wheels are laced and trued, the rim sidewalls are ground to provide a smooth braking surface for the rear V-brake. We build the Laser 2.0 wheels with 36 spokes in a 3-cross lacing pattern for a strong & durable wheel. Then mount knobby BMX tires that bite in the dirt, but also feature a rounded profile that rolls smoothly on neighborhood streets & driveways. Every Laser 2.0 offers a kickstand for parking that pride & joy up securely, and a safety bell to announce that the Laser has arrived.

Every Jamis youth bike uses size-specific items like grips, saddles and cranks that enhance comfort and control by providing the best possible bike fit. We focus on designing frames with low stand-overs to take much of the awkwardness out of getting on board and dismounting after. We trim as much weight as we can with lightweight aluminum frames on many of the youth models and use aluminum parts where possible (the limiting factor here is working within a youth-bike-appropriate price point) to work towards that make-it-as-light-as-possible goal.
