Ride notes
Power comes from the rear wheel (a ‘push’ vs the front-wheel ‘pull’ of earlier models) – smoother and more natural. Top-mode assist makes 12.9% gradients trivial. Walk-assist and start-assist help with hills. Folded size is unmatched.
Available sizes
One size (extended seatpost for taller riders)
