Ok parents, have you been doing your cardio all winter? I hope so, you are going to need it now to keep up with your kids on the 24" Prevelo Alpha Four! Riding to school or on your local city trails, the Alpha Four gives all the tools needed to get out and have a fun confident ride!
Canadian shipping only.
- Prevelo confidence-inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.
- Lightweight 6061 aluminum frame with custom formed tubing.
- Lightweight aluminum alloy fork with chromoly steerer.
- Tektro front and rear v-brakes.
- Quick release front and rear wheels for toolless wheel removal.
- Three piece crank with squared taper bottom cartridge bearing bottom bracket and ultra narrow Q factor.
- Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimeter.
- Shimano ALTUS 8-speed drivetrain. This 8-speed derailleur has a SHIMANO Smart cage. This unique pulley cage permits the use of a shorter pulley cage without comprising gear ratio width. Because kids’ bikes have small wheel diameters, rear derailleurs on kids bikes hang low and close to the ground. The Prevelo Alpha bikes use Smart cage derailleurs to keep things high and away from the ground.
- Shimano ACERA RAPIDFIRE Plus Shift Lever. Small hands have a hard time using twist shifters. We use reliable silky smooth thumb shifters. They are easy for small hands to operate, have an indicator display, and operate just like shifters on high-performance bikes.
- Replaceable derailleur hanger. If the derailleur takes a hard hit, the hanger can be replaced without repair to the frame.
- 11-34T wide span gearing gives riders plenty of range to spin up tough hills.
- 95% assembled. Just install the handlebar, seat post, front wheel, and pedals.
