Let customers speak for us
from 276 reviewsThe xrt frame itself is crazy nice! The build seems great and it looks amazing. J-dubs has been insanely great to deal with, called me multiple times to make my order cheaper with something he knew that I didn’t, shipped multiple orders together andreceived them faster and just been great to work with. Thank you

Great product enough for two kids break lines

The bike is insanely smooth and dead silent. The customer service has been pretty good as well, just waiting on a final call back.
Thank you JDubs

Easy purchase efficient shipping

Top quality products, top quality service! 11/10 amazing! Absolutely fantastic company to work with! Could not recommend them higher👍👍

My daughter races in sandy dirt and so far it's holding up

Worth the wait

I had to make a special shipping request and Juan handled it with eez. Shipping was fast too! I also got a custom number plate with said order and it looks fantastic! I'll be ordering more parts for sure

I was surprised with the quality of these. The fit and finish is excellent and the grip they provide is so much better for the kid, plus they seem like they are going to be so much more durable. Buy them. You won’t be disappointed.

This bike is amazing

Great addition to the Stacyc 12e

Honestly have no clue how these bikes are this awesome for the price. Shipping was super fast and putting it together was very easy. My kid loves it! Highly recommend!

Awesome bike and awesome experience with Jdubs all extras fit the bike perfectly and we are super stoked to race thanks again
