What we love about this bike:
- How lightweight the bike is - makes it much easier for a child to ride.
- So easy to shift, perfect for kids who have never done so before
- An intelligent design, taking into the size and ergonomics of children, to design a bike that makes riding easier and more fun.
- The “small hand reach” brakes, which enable even the smallest of hands to brake safely and with minimum effort.
- The high quality of manufacturing. This bike is lightweight yet super durable. Made to last so it can be passed down from child to child or re-sold.
- Woom is a sustainable company that values safety, ergonomics, handling, design, and non-toxic parts to create environmentally friendly bikes for kids.
"The WOOM4 is the best all-around 20″ bike we have tested. Rugged and nimble enough for moderate single-track riding, yet comfortable enough for street riding, the WOOM4 is the perfect bike to take your all-terrain rider." Online Bike Review Expert (Two Wheeling Tots)
