Are you thinking about buying a new eMTB with the aim of tuning it? It's important to understand that the motor decides whether you can tune it, and how easily.
Some bikes take a simple plug-in kit in 30 minutes. Others need a specific version, and a few can't be tuned at all. We've picked bikes that are straightforward to tune and told you exactly which kit each one needs to help with your research.
All of the bikes in our list below hit these two requirements:
1. They must be easy to tune (no motor removal)
2. They must be under £5000

Before you buy: three things to check
- Which motor it has. Our Kit Finder confirms it in 30 seconds.
- Whether it has a rim magnet. Bosch powered bikes with a rim magnet sensor require motor removal
- The bikes to avoid. Shimano EP6 or EP801 motors, Bosch CX-R motors, or bikes with ABS
