Summary of Reviews
We have read all expert and user reviews on the woom UP. In summary, this is what cyclists think.
14 reasons to buy
- woom's offers this bike in two sizes: the UP 5 with 24” wheels and the UP 6 with 26” wheels.
- Both sizes have clearly specified height and age ranges and size-specific Q-factor, crank length, saddle, handlebar width, and suspension travel.
- Reviewers say the electric assist builds confidence and allows kids to ride longer and further.
- A tester praises the Fauza motor's smooth and consistent pedal assist that's limited to 15.5mph for safety.
- Children enjoy the grounded feeling on descents and overall ride stability on beginner and intermediate trails.
- Parents can customize the intensity and maximum power output of each pedal assist level via the Fazua app.
- The UP's stem can be flipped to raise the handlebar height as kids grow.
- The Promax Solve ST hydraulic disc brakes have child-specific levers and offer great stopping power in testing.
- The 2.35" Schwalbe Rocket Ron tires provide good traction on dry trails, according to a reviewer.
- Experts are pleased with the responsive shifting and wide gear range of the 11-speed SRAM NX drivetrain.
- The RST F1RST air suspension fork is fine-tuned for lighter riders, and reviewers say it performs well.
- The battery can be removed and replaced with a cover (sold separately) to ride as an analog bike.
- The UP has internal dropper post routing and is tubeless compatible.
- woom provides a 10-year warranty on the frame, bars, and stem for bikes registered online.
9 reasons not to buy
- This bike's high weight makes it hard to maneuver on steep or technical descents, especially for smaller kids.
- woom warns the UP isn't designed to handle jumps over 12”.
- A reviewer recommends children lower or turn off pedal assist before downhills to avoid unwanted boosts of power.
- The motor only provides power once a certain input is given from the rider, and a tester says the threshold may be too high for younger kids.
- The battery must be removed from the bike to charge, and, at 7.5lb, it is quite heavy for smaller children to remove.
- Young or inexperienced riders may struggle to learn to use Boost mode.
- The kickstand is unnecessary on a bike marketed primarily for electric mountain biking.
- The 15.5mph top speed cannot be lowered for less experienced riders.
- A tester says the UP is overkill for city riding and wouldn’t function well as a child's sole bike.
Bottom line
woom's UP is a kids' electric mountain bike with a 250W motor and 252Wh battery. It's available in two sizes: UP 5 (24" wheels) and UP 6 (26" wheels). Experts praise the overall build quality, smooth assistance, child-specific components and geometry, and powerful brakes. However, the UP is heavy, making it hard to maneuver and unsuitable for technical mountain biking. Pedal assist is customizable, but the UP's top speed can't be changed. Controlling e-assist requires practice, especially Boost mode. While the woom UP is considered expensive, parents appreciate the freedom to tackle longer, more challenging rides as a family.Expert Reviews
