Let customers speak for us
from 139 reviewsThe kid was complaining about how bumpy the pasture is with no suspension. This is working well for him. We purchased the extra soft spring for the small bumps, since he won't be jumping any time soon.
The seat was exactly what we needed for my son’s electric bike. Very cost efficient, and shipping was much faster than originally expected. All around great company to buy from!
Excellent seller with equal customer service and pricing on hard to find parts
Ordered a new bike for my kid. Got dropped shipped from the manufacturer and got damaged during shipping. J Dubs sent me a new rotor right away.
No complaints! Kids love it!
my 5yr old son hits mtn bike trails with me. battery life on these things is impressive! hydraulic brakes make him more confident on the trail and he's even got a little small travel fork. this thing is sick! 10/10 would recommend.
wish it had a water bottle cage
These are very pretty and extremely well made, not for beginners though. I bought them for my daughters stacyc 16, once these are installed , moto boots will be a must
Kid loves his XRT 20. The front brake rotor got bent during shipping. J dubs customer service was awesome about sending out a replacement right away. They even gave some tech tips over the phone.
Perfect fit & easy to install. 13days to get this item to the centre of Australia could not be happier.
Awesome tire much better than stock. Absolutely love the way they look too!!
Was helped by a representative who was timely and efficient. Easy ordering service. Product came as ordered! Couldn’t be happier! Will be using JDubs again!
Bike is fantastic.My grandson loves it,
The perfect upgrade. We raced from 2-4yo and just switched to this throttle. So nice to have a better grip for the little guy. Wish we had it since the beginning.
Fits tight and works great 👍🏽👍🏽
My daughter loves the bike but this review is geared more towards JDub’s Racing and the their staff. I had a small issue which was not JDub’s fault. Val and the team got everything straightened out in no time and made everything right. I would highly recommend buying from JDub’s Racing if you are in the market for an e-bike. They also honored me as a first responder with a discount.
