Wheels size
The XR20 2023 bike is equipped with 20″ aluminum wheels when leaving the factory. The 20″ wheels are a good fit for folding bikes, BMX, or children bikes. In conclusion, you can use them better on-road, and less on technical terrain.
Brakes
For your safety, it is important to have quality breaks on your bike. Jamis XR20 has Rim brakes installed. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they are not nearly as effective as hydraulic brakes are.
