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.
Jamis' lightweight and durable aluminum XR.20 frame is easier to pedal than steel and features tapered and ovalized tubing to optimize frame strength and durability while offering the cool looks today's young riders appreciate. A six-speed drivetrain is ideal for most youngsters to learn how to shift and master. It's also enough gearing to get around the neighborhood or park comfortably, with just one single chain ring in front to simplify shifting. A double-sided chain guard keeps the chain in place and clothes and legs out of the chain's way. There's a protective derailleur guard attached to the rear of the frame to protect the rear derailleur from knocks, keeping it in adjustment longer for greater safety and control. A full alloy parts package, including seat post, stem cap, crank arms, seat post clamp, brakes, and rims reduces total bike weight and adds value. The XR.20's XC saddle offers lots of high-quality padding for comfort and control with a narrow nose so that legs can pedal freely without chafing.
