Let customers speak for us
from 517 reviewsGreat setup for our 2yr old. He’s in a way better position on the bike now. JDubs is a great company to deal with. Will purchase all our stacyc parts from them.
This bike absolutely rips. My 6 year old was coming from a Stacyc, and there’s no comparison between the two. So far, we’re very happy with the product.
Quick service, correct parts. A+ job
No complaints. The product came in on time. Easy installation. Made the bike more comfortable to ride.
My son outgrew his 12” ebike and bought this one. Perfect electric bike for my son! He loves it!
Great kit! My boy is able to ride faster and in control. I was worried about front brakes being too much for my 3yo but he hasn’t had any issues getting used to them
Great fit, very tight and durable
Insanely fast order processing time. They must have just been waiting around for my order it was that fast. Good item description, fast shipping, and perfect OEM fitment. Would do business with them again.
Jdubs was fantastic! When the package first arrived it was missing a piece. I wrote them an email late Saturday night and they had already created a label and packaged up the missing piece by Sunday morning. Great great products and even better service!
This brake is a must once kids start to carry speed! Total game changer and how the bike should be sold!
We bought this for my 3 year old to race
. He rides the tires off this bike. He races and has won all five races he has run. We have parents asking us what this bike is. It blows the Stacyc away on the track.
J-Dubs was amazing to work with. I purchased a Onewheel GT from them and they helped me through the selection, customization, and ordering. They provided great customer service throughout the whole process.
