An urban electric bike with a stiff steel diamond frame, distilled to the essentials with purity of form; a clean aesthetic and a speedy ride. Nimble and light, Upstart is the fastest way to get around.
Reviewed by the authoritative and independent A to B magazine, Upstart's reviewers report it "leaves all the clunky derailleur bikes searching for gears, and will outpace most electric bikes too". Not only was it reviewed as “blindingly fast for a 'legal' bike”, the Upstart was also deemed as "damned efficient: you put human and electric power in at one end, and road speed comes out the other.”
At the heart of Upstart is our automatic torque sensor AUTORQ™ system; an innovation exclusive to Momentum Electric. It measures your effort on the pedals and intelligently controls the 250W motor to provide assistance accordingly. The result is an intuitive ride and an excellent range from the 324Wh lithium-ion battery.
Upstart also boasts a SRAM Automatix gear hub. This two-speed automatic shifting hub changes gear automatically at a certain speed and does away with manual gear shifting. Coupled with the AUTORQ™ system, it makes cycling uncomplicated and an absolute joy.
Upstart is the perfect choice if you like to keep things simple for life in the fast lane.
