Woom UP 6 Limited kids' e-bike Cirrus Cloud

Description

Woom UP 6 Limited kids’ e-bike Cirrus Cloud is a children’s electric mountain bike (e-MTB) on 26" wheels with a Fazua drive system, designed for riders roughly aged 10–14 and 140–165 cm tall. In terms of design, it targets the higher-performance kids’ category: it combines a lightweight aluminum frame, an air-sprung suspension fork, and an 11-speed drivetrain so children can handle longer rides and off-road terrain when riding together with adults.

Frame and geometry

The foundation is the Woom Off frame made from ALU 6061 aluminum alloy with a 12×135 mm rear thru-axle, designed for sporty kids’ off-road use. The front end is built around a 15×100 mm thru-axle (compatible with the fork), which is important on a kids’ e-MTB for accurate tracking and stability under braking. The headset is integrated in a 1 1/8" size. The manufacturer does not state key geometry numbers (reach/stack, chainstay length), but the 26" wheel setup and more trail-oriented components reflect a focus on off-road control while keeping sensible agility for smaller riders.

Components

Electric assistance is provided by the Fazua system with 250 W power and 55 Nm torque, with assistance limited to 20 km/h; the battery has a 250 Wh capacity. A practical feature is the option to remove the motor together with the battery from the frame, so the bike can also be used as a purely “analog” MTB. Shifting is based on Sram NX: a Sram NX Trigger shifter (11sp) controls a Sram NX rear derailleur; the Sram NX PG-1130 cassette has an 11–42-tooth range and the chain is a Sram PC1110; 150 mm Woom ALU cranks carry a 28T chainring. Braking is handled by Promax Hydraulic disc brakes with 160 mm rotor up front and 140 mm at the rear. The Woom Off Disco Tech 26 wheelset uses 15×100 mm (front) and 12×135 mm (rear) thru-axles and a 20-spoke lacing pattern; Rocket Ron Addix Speed tires in 26×2,35" are aimed at fast rolling while maintaining traction in light to moderate terrain. The cockpit consists of 680 mm-wide Woom ALU 31,8 mm handlebars and an adjustable Woom Flip-flop ALU 50 mm stem with a +/-15° angle; the Woom ALU seatpost has a 27,2 mm diameter and 300 mm length, and the saddle is Woom.

Riding characteristics

The combination of an aluminum frame with thru-axles (12×135 / 15×100) and wide 26×2,35" tires boosts confidence in off-road tracking and stability when braking over bumps. The Woom Air Fork 24 air fork with 90 mm travel and a lockout (LO) allows the sensitivity to be tuned to the child’s weight and reduces bobbing when riding on asphalt or climbing. The gear range of 28T up front and 11–42T at the back, together with Fazua assistance, helps maintain cadence on climbs without needing extremely low gears. The stated weight of 16,6 kg is relatively low for a kids’ e-MTB and in practice translates into easier handling and more predictable control.

Who it’s for

Woom UP 6 Limited is intended for children 140–165 cm tall who ride regularly and want an e-MTB with components suited to real off-road riding (air fork, hydraulic disc brakes, 1×11). It makes sense for families where a child needs to match adults’ pace on longer rides or in hilly terrain; compared to typical kids’ e-bikes, the low weight and the ability to remove the motor and battery are key advantages.
