    Speedbox 3.0 or Volspeed for Bosch 4 gen?

    Just fitted a VOLspeed 3 and like that I can select speed limit each time its activated, display in mph. Biggest plus was no countdown as required at end of Speedbox ride and no delay for motor power wimhcih people say happens with speedbox module. Unless discount is large I'd get a VOLspeed.

    Volspeed tuning box for Bosch gen 4

    OK fitted! Took literally 5 mins to fit as I didn't have to remove the crank arm. Cable tied it all in place. Pwered up and accessed set up and selected the 28km/h option for a Pedelec. Then activated the dongle and set it to 20.5mph (though I see there is a 19.9 that I'll use in future)...

    Bruno, Thanks for the information. I will be interested to hear how your bike is woth the VOLspeed as I have a Supercharger 2 with E14 hub. Did the dealer detect tuning with the speedbox 3? Good to hear you had no problem getting the motor replaced. Great to hear the E14 performed well at...

    Thanks for the update and great to hear you are back up and running. But what was it that caused the Error 503 though? Dodgy connection?

    Yeah thanks for the feedback! We'll it's not an error 504. I'd have suggested fully remove and refit in case of loose contacts but you've tried that. Hopefully a one off faulty dongle. Keep us updated! Thanks!

    I emailed ebiketuning to see if they would do a discount on a few units if anyone wanted to be involved in a bulk buy but no discount. I see the Peartune for Bosch 2020 is only about £100 but again can't see much about it. I think ebiketuning was offering 5 euro discount with code Follow5...

    Bosch Error 504 With Speedbox 2

    Has anyone got any experience of the Peartune dongle? It claims to not require the countdown, displays real mileage and mileage value is retained if the dongle is removed?

    No he is on a Gen 3. I am still waiting for some good feedback on Gen 4 CX Tuning. Peartune state they have a number of their dongles working fine on Gen 4 so I am tempted to give that a go.

    Anyone tried one yet? Also in the market for a Dongle. SB3 seems to be successful but be interesting to know of the Volspeed doesn't need the count down process at the end of a ride?
