Let customers speak for us
from 393 reviewsI thought the adapter was faulty so I reached out and told them. They helped me troubleshoot and then promptly sent a new adapter. Turns out the battery terminal on my bike was in wrong and it wasn’t a faulty adapter at all. But the customer service was amazing! Real people running a small business. I would definitely recommend!
The stock drumb brake on the stacyc 12e is atrocious. My 3 year was struggling with the high lever pull force and limited braking, especially on downhills. Installing this disk brake kit is a game changer, lever pull is very light and nicely adjustable to suit small hands. Install is a bit if a pain in the butt due to the stayc rear and design but certainly doable in a couple hours. I did not have to bleed the new brake, but that might be necessary which requires some specialty tools. If you're taking your little one on anything more than a cruise around the neighborhood this is a worthy investment.
Perfect fit and easy to adjust to the correct height.
Very nice and wide. You do have to get nutsfor the screws and remove underplate. These are awesome
The one that came on the bike was bent during shipping . Jdubs sent it out no hassle fast shipping . Great doing business with them.
Wow! This kit is awesome, way higher quality than I expected! The shock feels like it was tuned perfect for the bike. Fits perfect and went together with ease. I am blown away. I will definitely be back if I need more upgrades. Also get the shimano shock! It is really good!
Just what my daughter wanted!!! Easy to install and looks great. She wanted to represent J-Dubs on her bike because they have been more than helpful with all our Pur-Speed needs. (Wear and tear). Thank you again!!!
Perfect fit for the original thumpstar 16in.
Perfect repair for the bike. My daughter rode off with the charger still hooked up and broke the insert piece off. One quick call to Juan and she was back on the track in no time. Exceptional service from that guy!! Absolute pleasure to do business with!!
Awesome tires. Bought em for my nephew and they are much better than stock staycyc tires. Now he grips and rips
Best thing out there, priced well, nicely made. STACYC 16eDRIVE BRUSHLESS.
Great option for toddler sized e-bikes. We had a blast adding the kit to her strider. She now refers to it as “our” bike. I will cherish the memories of “building” this with my 2 y/o daughter more than I ever would have by just pulling one out of a box.
Hang on, these things are fast! It took our 3yo a couple days to get the hang of the Pur Speed on his own. He was already very proficient on his Strider bike as well as a 16" pedal bike, so it was just learning how to operate with a throttle. We had to work on partial throttle and letting off/applying the breaks. Once he got the hang of that, he was off to the races, sitting, standing, trying to catch his brothers on their dirt bikes! If the video shows up, it shows him on 1/2 power, middle speed position on switch. Also, highly recommend ordering from JDubs. The support they offer is top notch, they even helped us with some questions we had during the holidays when they were technically closed.
JDubs is a pleasure to work with. I live in Hawaii and it is a pain getting ebikes shipped out here. JDubs made it easy and had the bikes delivered as soon as he got them! I ordered a XRT 20" Pro FS with triple clamps for my oldest who is turning 7 in February and a XRT 12" Fury eco for my youngest who just turned 3. My oldest was ripping it to its fullest potential after 2mins, going as fast as that bike would go. My youngest was up and going on the fastest setting with no kick start within 5 mins of figuring out some throttle and brake control. Both boys love em but the oldest wishes it was a bit faster and had more torque for holeshots. He rides a KTM 50sx so he knows power and the 52v leaves him wanting a bit more. Overall topnotch experience with JDubs!
