The Wabash rides very well with assist on. There’s a notable step between each level, and we found ourselves using Eco+ or Standard mode most of the time, with High reserved for extreme needs. Yamaha’s new speed sensor with zero cadence assist provided power from the first pedal stroke without lag. It’s also cleanly integrated, improving appearance and eliminating the all too common issue of lost function due to the wheel magnet getting knocked out of place. While the Wabash is a Class 1 bike that cuts assist beyond 20 mph, the system doesn’t feel like you’ve dropped anchor when pedaling beyond the assisted speed. It was slightly more noticeable off road, but this could be due to cadence being smoother and more consistent on paved roads. It’s also worth noting that during a particularly technical section where we got off and on the bike several times (and not always in the most graceful fashion), the bike never engaged power when not wanted.
