Woom детский горный велосипед Off 5 24in

Rear wheel was not dished properly, it was pretty far off to one side. Front wheel was better but not perfect. Spoke tension was also not very uniform. Brake levers were over torqued. Brakes are not very powerful, even after bedding in; they feel like organic pads, so that's probably why. Wish it used standard diameter grips since this 26" size is basically an adult bike. I'm under the weight limit so I took it on some singletrack. Its very stiff, I feel like it coulda been made more comfortable, but I mostly ride steel bikes so who knows. Good deal overall so long as you know how to build wheels. Its very light, which was my main criteria.

The bike is nice and light and I like the air fork for tuning, but the hydraulic disc brakes leak and are underpowered and rapidly glaze so they are noisy. Weve replaced pads and rotors and taken it to professional shops twice but the noise comes back so fast my son refuses to brake and wont ride it. Compared to the other Woom bikes with rim brakes, the amount of fuss and expense of professional bleeding and rotor/pad replacement for hydraulic disc brakes are a terrible choice for a kids bike.

Background -- bikes are my life, I've had many, and my kids started on balance bikes at age 3 or 4. I can fix anything on a bike, including building new wheels. We loved the Woom Original line of bikes. The Off bikes are not all that. The brakes are crap. Front brake had no power after 18 months, needed a bleed. The bleed kit costs more than the cheapest Shimano hydraulic brake (which works quite well). The rear brake started leaking at the caliper after 22 months, soaking the rotor, so zero stopping power. This bike only gets ridden 5 hours/month in summer, should need zero brake maintenance. The crank is a proprietary design, looks like you can't replace chainring. Derailleur hanger gets in way of inserting rear thru axle. Rear wheel was built wrong, a spoke is bent around a spoke head at the hub (assembly error; see right side of pic). Too many problems for what this cost.

Just commenting on the other review. I t does not come with a bottle cage but the down tube has screws so you can add one if you want. No hydration options on a mountain bike? No chance.

The bike is very smooth ride and very fast with little effort. Best feature of the bike is that chicks dig it. The bike is missing the option to carry a water bottle.
