Inspired Flow 20″ Bike

Description

Inspired Flow 20″ Street Trials Bike

The Inspired Flow 20″ is designed specifically for young riders who want to learn the fundamentals of street trials and develop their bike-handling skills. It brings the same trials-focused approach found on Inspired’s larger Flow models into a compact, durable package suited to smaller riders.

Its carefully developed geometry combines a short rear end with a balanced riding position, making the bike easy to lift, spin and manoeuvre while retaining enough stability for everyday riding. The 73° head angle and short-offset fork provide responsive steering and make the bike well suited to learning front-wheel techniques and other basic trials movements.

Purpose-Built Frame and Fork

The Flow 20″ frame uses 6061-T6 aluminium alloy with full-size tubing, a reinforced downtube and a custom bottom-bracket yoke. The yoke is shaped to provide clearance for the 24-tooth front sprocket while maintaining a strong and rigid frame structure.

The steel Flow fork uses oversized legs and dropouts for increased durability. Together, the frame and fork provide a useful balance of low weight and strength, allowing younger riders to control the bike easily while withstanding the demands of trials riding.

The rear triangle is designed specifically around the supplied 24:16 gear ratio. Compact horizontal dropouts work together with the CNC-machined Flow chain tugs to provide straightforward chain adjustment and a clean rear-end design.

Both the frame and fork use disc-brake mounts, allowing the braking system to be upgraded as the rider’s skills develop.

Quality Components for Young Riders

Inspired has selected components that provide reliable performance without unnecessarily increasing the bike’s weight. The cockpit combines an Inspired aluminium riser handlebar with a forged Trialtech stem, while the drivetrain uses Trialtech cranks, a KMC chain and a Trialtech sealed freewheel.

The standard braking system consists of Avid FR5 levers and BB5 mechanical disc calipers with 160mm Avid G2 rotors. Riders can also choose from several hydraulic brake upgrades for improved braking performance.

The wheels use strong Inspired 20″ rims combined with sealed-bearing Trialtech hubs, while 20 x 2.35″ Duro tyres provide a practical setup for street trials riding.
