Electrical Pedaling Assistance

How does it work?

The pedaling support system drives the pedals and not the wheel, which allows for a more natural leg movement. The system guarantees 360-degree support of the pedaling motion, with focus on critical positions. Moreover, because the system doesn’t drive the wheels directly, the user can still use all 8 (or 11) gears of the bike.

The electric pedaling support system lets the user decide how much of their own strength they want to use while cycling. 6 levels are available to the user; the higher the level, the more support is provided. The levels range from barely any support to full support (like a mobility scooter). The interplay between the chosen support level, the chosen gear, and the user’s own power output will determine the cycling speed.

HOW FAR CAN YOU RIDE WITH OUR BATTERIES?

This is the most frequently asked question we are dealing with: What is the range of our batteries? Since many things of an electric tricycle are determined electrically and mechanically, this question seems to be easy to answer. However, the tricycle is moved by a person. The person on the bicycle appears to have such a large influence on the range that a difference of up to 100% can occur.

DIFFERENCES IN THE OPERATING RANGE

The most extreme example of a difference in range was a couple who had purchased two identical electric tricycles from our battery supplier. The gentleman had a range of 50 km, but the lady had a range of 100 km. Both said they were good at pedaling. How, then, can there be such a difference in range?

The supplier of our batteries turned these two tricycles literally inside-out. After performing several dynamic and static consumption tests, the result was that the bicycles had almost identical consumption. Both batteries also had the same capacity. The conclusion that can be drawn is that the human factor makes a huge difference in determining the range.

THE FOLLOWING HUMAN FACTORS ARE RELEVANT TO THE OPERATING RANGE:

 The weight of the driver

• The own contribution of strength applied to the pedals (power)
• Tyre pressure

Because the human factor is difficult to influence, we excluded the human factor, and we have adopted an average minimum and maximum range for our tricycles. Our tricycles consume approximately 8Wh – 20Wh per kilometre.

DIFFERENT KINDS OF BATTERIES

Below are our batteries with their minimum and maximum range based on the calculation of the supplier with the consumption value of our lightweight tricycle. The following consumption values are applicable for flat roads and without wind.

• 36V/10.4Ah/375Wh battery, min. 25 km & max. 75 km – our standard battery.
• 36V/17Ah/612Wh,  min. 40 km & max. 120 km – 63% higher capacity

The minimum range is achieved when the driver contributes little/nothing or when cycling mainly in the highest support position.

The maximum range is achieved when the driver cycles himself and requires little extra support at normal speed. Cycling takes place in an average support mode.
