When I bought my blue VX-1 brand new in 2009 I was able, at 25 degrees Celsius, to achieve a 62.2 km range from a full charge down to getting the BuSULt warning. Yesterday I decided to do a similar deep discharge just to determine the pack capacity now, seven and a half years and 46,360 km later. On the same test route and at the same temperature, that original pack yielded 62.5 km! Must say, I'm impressed with the GP cells as well as the overall engineering and build quality of the bike despite the terrible management of the company.
All I've done over the years is ride and charge it regularly year round, never used an extension cord, replaced the tires twice and replaced both brake sensors after one failed not too long ago. The failure had resulted in flickering brake lights, balky charging startup and eventual quitting of the left/right handshake 'GO' sequence, but all resolved beautifully just by unplugging the dead sensors and plugging in new ones. So...three cheers for my splendid Vectrix, and I hope to get at least another seven years from her. I just bought a winter windshield, Vectrix-specific Tucano Urbano handlebar muffs and leg cover, so I'm set for a warm and comfy winter of riding!
