EPS V4 Power Unit
The new Power Unit, its fairly slender shape making it compatible with all the seat posts on the market, is quick to fit with one of the two different adaptors, the choice of which will depend on the size of the post. Even longer life for this, the sector’s leading battery, thanks to a 10% increase in its charge capacity, meaning it rarely needs charging.
