Brilliant!
If you’re buying for a Bosch bike the biggest challenge is pulling the crank, but a £5 crank puller from eBay and a few minutes on YouTube made that pretty simple. Once that’s done installing and using the chip is a piece of cake. If you’ve had your bike a while, it’ll be like your first time on an e-bike again. The beauty of the V4 is that your speed, distance etc is all still accurate. Very happy with this.
