Woom GO 4
Perfect bike, nice design and color, and the most important it is really lightweight compared to other bikes even smaller than this. It is comfort and safe. Nothing negative to say.
6/16/2026
woom built the GO 4 as the first geared bike in the GO line, and the microSHIFT twist shifter comes paired with a child-friendly gear indicator that uses terrain graphics rather than just numbers. A 6 to 8 year old can glance down and know which gear matches the hill or the flat in front of them without counting or guessing. Seven gears with an 11-28T cassette give enough range for real variation in terrain, and the 110mm child-specific cranks keep the pedaling motion natural for this age group. The quick-release front skewer makes wheel removal fast, and the ABC fit guide on both bars and seatpost keeps sizing dialed as they grow. Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.

Magic amazing bikes
Woom bikes are just so amazing. Each time we get a new one the kids just jump on it and 10 minutes later they master a new skill - first just the balance which took the longest for both of them, then pedals (10 min learning curve) and now gears which took no time as well. I am so impressed and happy they get this joy.

Bike was unusable
Break cable was apart from the casing. Tried to put it back in, couldn't. Took front/left break apart and one of the plastic pieces broke. So don't try to fix this bike yourself. Took it to my local bike shop and they said they deal with this a lot and we will call you when it's ready to pick up. The breaks aren't standard, so they need to wait for the part. It's been about a week.

The Best Birthday Gift Ever!
The Best Birthday Gift Ever! We gave our 6-year-old the woom GO in Pink for her birthday, and its been a total game-changer. The vibrant "hot pink" color is stunning and high-visibility, but the real magic is the weight. Its so lightweight that she can handle it, turn, and restart on hills with total confidenceno more "it's too heavy" frustrations!

Great bike!
My 5 yr old son went through 4 different bikes. This one was light, great handlebar distance, the middle post is safer than others and the brakes were easy to access!My son was afraid to start using the pedals on the last 3 bikes. On this one it took only 1 time: within 5 minutes he started pedaling. The next day he pedaled on his own! Totally recommend!
