Wheels size
The wheels on 3900 are the 26″ aluminum type. Being a little smaller, these wheels will fit both small and tall riders. However, you will need increased suspension than in the case of 29″ wheels.
Brakes
For your safety, it is important to have quality breaks on your bike. Trek 3900 has Rim brakes installed. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, you could spend a little extra and get a bike that has hydraulic brakes.
