About this item
  • Only compatible with Shimano EP800. Not compatible with other Shimano motors or Giant e-bikes. Full motor support speed independent. Correct display values up to approx. 23 km/h.
  • This + E-Tube port version is compatible with a Di2 derailleur or a satellite system switch thanks to the additional E-Tube port
  • When the lights are OFF, you can drive at unlimited speed. You simply turn off the chip function by activating the lights. If you want to use the tuning independently of the lights, do not connect the red plug during installation so that the SpeedBox is always active. If you don't have a light on your bike, the SpeedBox 1.3 is always ON.
  • A step by step installation video can be found under the following link: https://www.youtube.com/watch?v=ES7kvsALX1c&t=248s&ab_channel=SpeedBoxTuning
  • If you want to install a SpeedBox into a brand new bike, you need to ride at least 1 km on this bike before starting the chip for the first time. Legal note: e-bike tuning chips are not permitted in the scope of the German Road Traffic Regulations. Use is at your own risk and responsibility. We accept no liability for any damage.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
