I've owned three ebikes. On a five-star rating system:What did you land up with instead and why do you wish you had gone with the Nevo3?
* (not recommended) : Kalkhoff Integrale; 11-speed Shimano Alfine Di2 hub gear
** (not recommended) : Riese & Müller Homage GX; E-14 Rohloff
**** (recommended) : Trek Powerfly 5
The Kalkhoff (4,000 km) and Homage (18,000 km), despite being fabulous bikes to ride, failed repeatedly in terms of reliability. None of their failures was covered by warranty (a major mark against those brands). The Trek Powerfly (9,000 km) has had one minor glitch which was fixed promptly and at no charge.
The Nevo looks like a solid ebike with a sensible way of mounting the second battery – one of the Homage's weak links (literally). I suspect that the Nevo could prove to be more rugged than the Homage on rough roads and trails.
