120mm Brake Rotor - Style C

I was hesitant at first in the purchase of the aftermarket throttle,
It feels like it works even better than the stock one in response, and I like that it has a quick disconnect plug so that you don't have to pull the panels off to get to wire connector.

Great product. JDubs racing are highly recommended.

The best bikes. Jdubbs is the best!

The kids are loving this w bike.
Jdubbs is gemreat to work with and highly recommend!!

I 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.
