    Switching Bosch hub (SPH) to Nyon

    I think the system sucks, just love my Nyon. The base wires are the same, it’s super easy to change and you will be so happy.

    This would have been very easy to allow the user to set these parameters in one of the setup screens??

    Volspeed tuning box for Bosch gen 4

    Finally go around to installing the V4 on my Trek Powerfly 9E. Took it for a couple rides and it felt great to go past 31 KMPH without having the pedals feel like they were dead weight! I set mine to 42KM and might actually just set at 40. I am a little concerned about the power off procedure...

    Volspeed tuning box for Bosch gen 4

    I plan on installing mine this weekend. I have a Trek Powerfly9 E and do more pavement and hard gravel than trails so having a few more KMPH will be nice.

    Switching Bosch hub (SPH) to Nyon

    I could not find any information regarding changing from my SPH to a Nyon but am happy to say it was very easy. The guy at Trek said the wiring was the same at the head unit, so all it did was change the two contact wires from the hub display to the Nyon. I had purchased the upgrade kit, which...

    Powerfly 9 equiped changing Bosch SPH to Nyon

    Hi, I can't seem to locate a thread that shows anyone has changed their Smartphonehub display to a Nyon? Conflicting reports on the wiring, do I have to change the wiring to the motor or can it be converted at the mount? Also, sounds like the motor doesn't need to be dropped. I added a front...

    Powerfly 4 Powertube 500 to 625

    I apologize if this has been answered, but I can't seem to find a conclusive thread......but will the Powertube 625 fit in my '21 Powerfly 4? I want a spare battery and thought I might as well order the 625 for an extra $400. Thanks

    What is volspeed V4?

    Just ordered the V4, I live in BC Canada so it looks like about a 2 week journey. Will be putting it on my 2021 Powerfly4. Just had a new motor installed when it failed after only having it 5 months. It started skipping, similar to a worn our socket or chain, shop even replaced 2 (smaller) cogs...

    Trek Rail light

    I did pull the rubber grommet out and it had a little picture of a light on it so I knew what it was meant for. I ended up removing 2 small screws on the charger port and easily found the wires. Had the shop update my settings on the Purion and everything works perfect.

    Trek Rail light

    I just have the Powerfly 4, assuming that if the front wires were easy to find the back ones should be too. I will take my cover off and see. thanks

    Trek Rail light

    Hi, what perfect timing. I just installed a Lupine on my front handle bars and just got the Supernova tail light in today. Very easy to find the front wiring, just had to take out the lock and top battery connector and found the wires snap tied in a loop. Plenty of room to work. Now the back...
