Key Electric Assist Technologies For Converting A Tadpole Trike Into A Pedal Assist/E-Assist System - Part 5

Technology Benefits: It is all about the Experience:The first and foremost component in deciding an electric bike system is experience. What kind of experience do you prefer? Some may prefer the pure experience of electric movement. The is the first and foremost experience one can relate to.

A mid-drive system such as the one from Utah Trikes: with a picture shown below is regarded as a good mid-drive add-on:

Figure 8 - A Mid-drive electric bike system from 8FUN and sold at Utah Trikes

This system is quiet, reliable and it does move you well. The system operates on a throttle or an in-built crank sensor. The delivery of power is fairly raw and un-modulated and can be controlled through the controls. When activated by throttle, the chain moves so one needs to move the feet with the crank to keep up with the motor speed. The level of control is not as fine as you will experience with a Bosch mid-drive system. Compared to a Bosch mid-drive system, the 8Fun system is an order of magnitude quieter. In a nutshell, a Bosch system is noisier but provides a level of control through you feet expected of a high level eBike system. 8Fun/Bafang system lacks that control but provides much quieter operation. Let us summarize the comparison in a table below:

Table 1: A simple comparison between Bosch and 8Fun/Bafang

Bosch eBike System 8Fun/Bafang eBike System
Noise Level High Low
Refinement of Control High Low
Throttle Control Absent Present

The experience becomes a significant benefit for many avid bike riders. The more of an experienced rider you are, more you will gravitate towards the refinement of control. Hence the much celebrated success of the Bosch system.

The experienced bike riders expect a natural flow of power. They detest delivery of raw power. However many noveau electric bike riders may prefer just the raw power delivery. They are so exhilarated by the experience of the raw power, they are as yet not ready for the natural flow of power. That experience can truly be appreciated by pure cyclists.

Now, how do the direct drive motors deliver the “natural flow of power” experience. In essence, direct drive motors with inbuilt torque sensors deliver “Refinement of Control without the Noise Directly to the Wheel”. That is the kind of experience you can expect from the following systems (listed alphabetically):

  1. BionX (;
  2. Falco ( or;
  3. Go Swiss (http:// );
  4. Neo-Drive (

Which one is the best among the four above is a topic for another discussion.

Now let us quickly wrap-up some of the other key differences between the two technologies:

Table 2: A Short Comparison between Geared Mid-Drive and Gearless Direct Drive Technology

Geared Mid-Drive Gearless Direct Drive
Natural Flow of Power Poor to Good Very Good
Hill Climbing Good Fair
Hill Climbing Efficiency Good Fair
High Speed Efficiency Fair Good
Overall Efficiency Fair Good
Regeneration Non-Existent Present
Wear and Tear on Chain/Derailleur Etc. Heavy Non-Existent
Wheel Maintenance Non-Existent Light to High
Quietness of Operation Poor to Fair Very Good
Throttle Operation Non-Existent/Unsafe Existent/Safe (Not in all brands)
Number of Gears Limited No Constraint
