VOLspeed V4 Tuning Chip for Giant Syncdrive Pro 85nm (2022) Full Review

In this blog post we are going to review the VOLspeed V4 tuning chip for 2022 Giant Trance X or Reign E+ eBikes fitted with Syncdrive Pro 85nm motors. Before we start, please note that removing the speed limit on your eBike can void your warranty, derestricted eBikes are illegal and only to be used on private land.  


The VOLspeed V4 tuning chip is an updated version designed specifically for the 2022 Giant Syncdrive Pro 85nm motor, commonly found on the 2022 Trance X or Reign E+. 


- Plug & Ride with no programming required

- Simple activation via the handlebar controls

- Full use of Speed/Distance on your display 

- Option to set an activation code to prevent unauthorised use

Plug & Ride

The key difference between the new V4 & old V3 is that the new version requires no initial programming. This is great news for riders that want a plug & play solution, removing the chances of any human error during setup. Over the last 18 months we found that many riders found the initial programming on the V3 a little bit confusing which resulted in delays with setting it up. 

Tamper Detection

The majority of errors are caused by riders consistently exceeding a high speed limit (>45km/h). As a result the V4 will only allow you to set a new max speed up to 45km/h. VOLspeed have also improved the anti-tuning technology to reduce the chance of errors further, even on the most recent software update.


VOLspeed are regarded as one of the most reliable tuning chips for the Bosch motor. This new version now brings all of those popular features across to Giant owners. This is now a true plug & ride solution, giving riders full use of their display & ride control app with the added benefit of an increased max speed capped at 45kmh.
