Product Features

Designed around the Specialized Turbo Levo for todays slack and long 29ers and 650B bikes. However, it will work well on bikes with 27-28 degree seat stays, but will be too long and need the end trimmed shorter still.

The LARGE Rear Mudhugger is an all new design for the modern full suspension bikes that have low seat stay angles of 27 deg down to 22 deg. This is an extra long Hugger that is designed to be trimmed down to fit your bike perfectly.

The rear fender braces are designed to be custom-cut around cable stops/guides and other unique seatstay/swingarm shapes and features. Some frames have assymetrical stays, like found on EVIL bikes, and may not fit or will require extensive customization to fit. 

The Rear Mudhugger works well on all bikes, providing they have disc brakes.

Once fitted to your bike you will hardly notice it’s there, and you would stay dry and clean for much longer!

Kit includes fender, 6 zipties and protective/non-slip heli tape.

Please, ensure you use the helitape provided with the rear mudhuggers. Invisiframe or electrical tape are not sufficient to protect your bikes paint and frame. Also note to periodically check that zip ties are tight and that the heli tape is inspected and replaced before it wears out. 

The installation is easy and can be done in a short period of time. Find the installation video here.

Volspeed V4 has an easier and faster plug-n-play installation (no setup required)

New speed limit of 28 mph (45 km/h) on V4, where V3 has unlimited speed (more prone to errors, however, they are extremely rare)

Volspeed v4 is fitted with much more error-proof engineering.

The Volspeed tuning kit comes with original plugs and color-coded wires for an easy and perfect fit. Installation manuals and videos provide step by step detailed instructions and are easy to follow and understand. The Volspeed does not require any diagnostic tool for installation.

The tuning module is plugged into the connections of the drive unit. These are located under the left engine cover. Depending on the type of bicycle, you will need different tools to remove this cover. Most of the time you will need an ISIS crank puller and a Torx TX20 wrench.

When connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation as easy as possible above. Also, our customer service is always here to help! 

Activation: After successful installation of the tuning kit, please activate it on the speedometer. Press "minus" for 3 seconds while standstill or while driving.
