Features and Specs


Motorino CTb is designed as bike to replace your car in your daily use in the city. It is built to offer such a comfort that you enjoy riding it for hours without getting tired. The power train offers more power than you need in moderate hills but can provide a power that makes you feel riding on flat on street as steep as California street in SF.

As this bike is designed for your daily life, it is equipped with large front and rear racks transforming it into cargo bike when you need to load it. For the extra commuting comfort Motorino CTb is equipped with a cruiser handlebar which height and angle can be quickly adjusted by the quick release. The seat post is also spring loaded adding extra cushion.

The Motorino CTb features a high speed 500W continuous and 1200W peak power motor providing whooping 80NM torque through the built-in speed/torque converter. In terms of performance these bike is more powerful than any other 500W rated bikes. The quick starting torque allows you to accelerate faster than a gas scooter from a still stand without the need of gearing up your mechanical gears.

The Motorino CTb have two control modes: “power-assist” provides nine user-selectable levels of assistance that are automatically engaged when the rider pedals, or there is “power on demand” delivered proportionally with a twist of the throttle-grip. Compare to other bikes the throttle is active on “0” level of assistance.

The battery is locked into the downtube for better weight distribution and can be unlocked and removed by quick release lever. With the highest “energy density” currently available, the surprisingly light and small 48V 10.4 Amp-hour LG cell Lithium-Ion pack can power a 30km range in regular city riding, without any pedaling. The high capacity pack of 15 Amp-hours combined with the higher voltage translates into more total energy storage and therefore more range: over 30 km on electric power alone is possible, more than 100km with moderate pedaling.

It also features:

  • Shimano 7-speed hyper glide drive-train with Shimano Tourney derailleur and trigger-shift shifter,
  • 160mm Tektro front and rear disk brakes
  • 26” double-walled ALEX alloy rim with stainless-steel spokes
  • 26” Schwalbe Big Apple Kevlar protected tires
  • Shimano Acera 7gears with Revoshifter
