from 368 reviewsCustomer service was awesome from start to finish!
Great customer service
Great kit and very well thought out. This gave my kid the confidence to ride her stacyc on Trails with a downslope that she would walk with the stock drum brake. You do need a means to bleed the brake since you have to disconnect the caliper from the hose to route it through the stacyc. so if you don’t work on bicycles with Shimano brakes the. You’ll likely have to take it to a shop to get it bled after Install. All that being said when my kid sizes up to the 16”stacyc, this will be going on before she even gets to swing a leg over it.
It’s a standard bicycle chain. A little shorter than normal but longer than what was needed for the 12” stacyc. You’ll need a chain breaker to install.
Amazing bike and even better customer service!!
Had issues with shipping, contacted them and it was resolved the following week without hesitation. Great company
The Xrt met and exceeded everything we were looking for and my son hasn’t gone a day without riding. The quality of the bike is unmatched for the cost and we will most definitely be back for more as the kids grow. Can’t wait for the company to grow and see what they have in store for these mighty little bikes
My little girl loves them on her 12e
Very helpful highly recommend
Frankly I wanna say thank you for the successful shipping to my country
