Dr.Wolfgang Volkrodth : nominal 100W e-motor for assistance is sufficient

The electric drive of the bicycle is interesting as a starting point, because the development of the bike was of a different weight than the motorbike or motor vehicle. In order to find as many buyers as possible for bicycles, everything technically possible had to be tried and done so that a limited radius of action and a facilitated handling of larger gradients could be achieved with limited muscular performance to reach.
Original:
Der Elektrofahrbetrieb des Fahrrades ist insofern als Ausgangspunkt interessant, weil die Entwicklung des Fahrrades in ganz anderer wichtung als beim Motorrad oder Kraftwagen lief. Vorgegeben als nahezu unbeeinflussbare Naturkonstante ist beim Fahrrad das mittlere menschliche Muskelleistungsvermögen von 50 bis 100 W. Um für Fahrrader möglichst viele Käufer zu finden, musste bisher alles technisch mögliche versucht und getan werden, um mit begrenzter Muskelleistung einen groben Aktionsradius und ein erleichtertes Bewältigen grösserer Steigungen zu erreichen.

The aim of the invention is to find a kit for the retrofitting of normal bicycles to electric bicycles, which is easy to assemble, can be operated in a narrative manner, can be manufactured cost-effectively, can be adjusted in the range between approximately 5 to 25 km / h of vehicle speed, braking and gradient energy is not in mechanic brakes, but rather partially into the battery, and has a good efficiency and thus a sufficient radius of action with a limited battery weight.

Practical tests have shown that, in the case of electromotive auxiliary drives for bicycles, the disengageable transmission of force from the electric motor to the bicycle by means of a friction wheel, V-belt or second chain transmission losses between 30 and 100 watts. This is too much and leads to high battery weights and ultimately increased rolling friction and reduced climbing capacity.

An output wire for phase A is connected from the left terminal of capacitor C1 to the phase A input of the motor. The output wire for phase B is connected from the left terminal of capacitor C2 to the phase B input of the motor. The output wire for phase C is connected from the left terminal of capacitor C3 to the phase C input of the motor.
Test results using a motor configured as in FIG. 4 are as follows:

I have watched the evolution of the brushless hub motor over the past 20 years with great enthusiasm, and as they have become more powerful, more efficient and a hell of a lot lesser cost, I seen some reliable 450hp motors for less than $60, I have loved it, the ONLY problem is power, the batteries are probably the #1 hindering factor, the price of quality & reliable batteries is ridiculous, I working on a project that would use the principle of regenerative braking, having one wheel with a motor that also supports regenerative braking, but have another more powerful motor converted for the sole purpose of regeneration, it won't produce an Overunity effect, but I think more people will buy e-bikes if they can get twice the distance on half the power from a battery that's also half the weight (free bonus)

Can you point to where you have seen a reliable 450hp motor for less than $60? Did you really mean 450 Horsepower?
