            "..... FITS 99% OF ALL BIKES "

Dr.Wolfgang Volkrodth : nominal 100W e-motor for assistance is sufficient
http://translationportal.epo.org/emtp/translate/?ACTION=description-retrieval&COUNTRY=DE&ENGINE=google&FORMAT=docdb&KIND=A1&LOCALE=en_EP&NUMBER=3024398&OPS=ops.epo.org/3.2&SRCLANG=de&TRGLANG=en
translated:
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 average human muscle-power-potential from 50W up to 100W"
             Do not trust 100% technical language translations: you only get probably 50% knowledge

http://translationportal.epo.org/emtp/translate/?ACTION=description-retrieval&COUNTRY=DE&ENGINE=google&FORMAT=docdb&KIND=A1&LOCALE=en_EP&NUMBER=3033825&OPS=ops.epo.org/3.2&SRCLANG=de&TRGLANG=en
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.

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?

e2matrix LOL, I do so apologize, God only knows how, but I meant to put "Watts", I feel dumb, sorry for my inadvertent typo, yah, I'd LOVE a 450 HP electric motor for $60, I could do 120 mph while hauling 2 tons of load, LOL, thanx for telling me sir.

a 450 Watt motor is not very powerful, if the total weight of the rider, bike, motor and batteries are less than 180lbs, your good to go, but for experimenting with converting for use with generation, I prefer gearless btw, less resistance from the friction of the gears themselves

I have made myself an e-bike with a large gearless hub-motor. It is rated to 800 Watts, but when I look at the specs for the brushless motor on my 1/8 scale truggy, that small sized motor is rated to deliver 2800 Watts peak.
The e-bike battery pack consist of 10S 30C LiPo with a 60A BMS with bluetooth connection to Android phone. Batteries are bought at Hobbyking.com.
The electric current readings peaks 75A@40Volt at full throttle from slow speeds, or approx 3kW with tremendous torque at that low RPM. The rear hub motor is very powerful, but is for sure capable of much more power without damage. The only concern is the spokes between the hubmotor and the 28 inch rim.
From the three phase motor connectors, it is possible to regenerate some power. So I have bought a 1500Watt step up converter and a three phase rectifier. The converter needs at least 10VDC in to work. The rectified three phace is pretty damn smooth. I did a test with it and the regeneration works great. However, the temorary wirings looks like an IS-bomb, so I need some time to clean up the wiring :-)
Another concern is the input current to the converter. If I want to charge the battery with 6A at 36-42V, I need an input current at 24A. 6A charging current isn't much, so by tuning this up to 10 or 15 A we are talk 40-60A input at 10V which is not very practical amd the converter is limited to 30A input current, while input voltage is rated from 10V to 60V. Output up to 85V.
