Our top pick for the Specialized Levo Gen4 is the Speedfun Ultra. Released in September 2025 it offers a simple solution that just works.

Here's why you'll love this kit:

Plug & ride installation - no complicated fitting, just connect to the speed sensor (on the motor)

Best Tuning Kit for Specialized eBikes with TCD Display

Speedbox 3.1 B.Tuning for Brose Specialized eBikes

Unlike the previous two models, this Speedbox is fitted to the motor itself. Due to how the TCD is fitted, it requires a different type of tuning kit. Installation does take a bit longer, you'll need the correct tools to remove the cover from the motor to gain access. Here's why riders love this tuning kit;

 

• Simple activation using the handlebar controls or Speedbox app
• Custom max speed, trip tracking & diagnostics 
• Lifetime warranty 

If you are looking for a cheaper option and don't want the advanced features, you can opt for this standard version (same performance just none of the bluetooth connectivity)
