The Alpha One is the smallest pedal bike in the Prevelo lineup and is the perfect starting point for the youngest cyclists—easy to learn on and the ideal first bike, with short cranks that fit little legs perfectly and a THRU-TUBE frame design that offers class-leading low saddle height.

It's packed with features to get little riders off to the right start, including:
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 alloy steerer.
Front and rear v-brakes with small reach brake levers.
Rear coaster brake (removable with optional freewheel kit).
Front hub with low profile rounded hex bolts and no harsh edged nuts for little legs to knock against.
Three piece crank with squared taper 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.
95% assembled. Just install the handlebar, seatpost and pedals.
