On the basis of one of the most beautiful frames, using branded quality components, we decided to assemble the most powerful known electric bike of the CityCoco form factor.
As a result, we obtained the highest possible efficiency for the electric motor and controller, as well as a peak power of 20 kW.
Acceleration dynamics is comparable to sports bikes. At the same time, the rated power of the engine does not exceed 3 kW, therefore, a driver's license is not required to ride this electric bike in Ukraine.
If you do not need such power and high torque, for example, now you are just learning to ride, or you prefer a quiet ride, then this is not a problem. Power, torque, the response of the electric bike to the throttle handle, and much more can be independently adjusted within wide limits using a computer. It is even possible to achieve smoother starting and acceleration than the weakest 800W sitikoko.
Now we'll show you what you pay for when you order the 2020 CityCoco Long Range, redesigned by RIDE.
1) Engine. We used a motor made by the best electric motor company in the Chinese market, QS MOTOR. Its real rated power is 3 kW, but it has a significant power reserve. We had long planned to use a similar engine in CityCoco, but QS MOTOR does not make engines of suitable size, so we had to order the manufacture of a special rim, where the engine itself is mounted.
The wide aluminum wheel rims improved the heat dissipation of the engine, which made it possible to deliver such power.
Please note, although this is a wheel motor and there is no gearbox in it, this motor has a very high torque starting from the lowest rpm.
2) Controller. For such a powerful and high-quality motor, an appropriate controller is also needed. We used a Kelly KLS 7230 controller. It is a very robust sine wave controller with high efficiency, programmable for many customizations. The manufacturer claims up to 300 amperes of phase current, but according to our measurements, it exceeds 420 amperes. We set the battery current up to 270 amperes so as not to accelerate battery wear. With an operating voltage of 77.7V batteries (assembly 21S), this gave more than 20 kW of power.
3) Speedometer. Since Kelly's controllers don't work with traditional cheap speedometers, we had to use the 750C branded programmable trip computer. It has a large color display that shows not only speed and total mileage, but also power consumption in watts per hour. This will allow you to roughly calculate how much you will drive under certain driving conditions.
4) Batteries. In the minimum configuration, you can buy CityCoco Long Range with standard 60V batteries, which we use in other models,
but the maximum speed will be 67 km/h, and the power is up to 14 kW
To raise the maximum speed to 85 km/h and power up to 20 kW, we ourselves manufacture batteries using higher-current cells, and a voltage of 77.7 V instead of the standard 60 V.
5) High efficiency and reliability of electronics. The engine from qs motors, unlike standard sitikoko motors, has a high efficiency not only at high speeds, but also at low ones.
This provides significantly more mileage in urban mode with constant acceleration, or when driving off-road. When driving in a straight line, the mileage increased by more than 10%, when using two batteries with a total capacity of 77.7v 54ah, you can drive up to 230 km at a speed of 35 km/h or up to 160 km at a speed of 55 km/h.
Buying a new Long Range version with a Kelly controller and qs motors, you can not be afraid that one day it will stop driving for no reason.
And most importantly, what the owners of CityCoco have been waiting for with 12-inch wheels are low-profile tractor tires.
Now the CityCoco with alloy wheels can be driven on any off-road and snow.
It was very difficult for us to get these tires, because they are not on sale in China, and we ordered their production at a European factory.
After 3 months of rigorous testing, nothing happened to the frame of the test bike, so we decided to leave the standard Chinese frame. If you want a stronger frame, we can make it ourselves, but this will significantly affect the final price and significantly increase the assembly time.
The front shock absorbers are spring-oil, the rear are full-fledged gas shock absorbers with the possibility of pumping. The driver's seat is the softest of all CityCoco models. The light fixtures are also the brightest and can be clearly seen even on a sunny day.
Both batteries are removable.
There is a luggage compartment under the passenger seat, which is locked.

If you already have a CityCoco Long Range version and would like to have the same electrical filling as in the new version, please contact us. We can completely redesign your e-bike by replacing the motor, controller and display, and installing a footboard sensor.
