Innovative electric bicycle

I saw something similar on YouTube, so I can't really call it mine.

https://www.youtube.com/watch?v=d9brryyFeBQ

Maybe somebody does this already, I haven't seen it, but seems to me
best would be to put a 16 tooth freewheel on the geared motor shaft and
connect it to the largest sprocket on the crankset.

I'm planning to use a cordless drill.

The cranks will turn when the motor is running, so it might be a good
idea to have foot pegs. Also, when pedaling the motor chain is driven,
but that's a tiny loss of efficiency. The cordless drill has a slip
clutch, so there is no concern about massive torque on one's feet.

Otherwise it looks very easy except for mounting the motor.

You might look at the "Whizzer motor bicycle". It had a gasoline
engine driving the rear wheel which eliminated all the fuss and muss
of having the pedals spinning around when motoring :-)

As the rear wheel was driven through a vee belt there was a simple
tensioning pulley to allow the engine belt to be loosened when
pedaling.

Nowhere near as simple as mounting the engine and just strapping a chain
around the other crankset sprocket. Mounting the engine isn't simple,
but the design couldn't be any simpler for what it does.

The pedals spinning is a drawback if end are concerned about injury? You
could also hurt yourself while "exercising" or "popping the top on a
tinnie"? So there is no reason to wear a helmet while cars are zipping
past you at 60 mph, but spinning pedals are a health hazard? That's so
confusing!

To stop the pedals from spinning, you just let off of the throttle.

I do have to figure out where to put foot pegs. My crank arms are kind
of long. Foot pegs are common accessory on a motorcycle.

Besides the fact that there is no simpler design, which matters a lot
when you build something, the spinning pedals provide dual power. It's
also very efficient given a dual sprocket crankset. It's just the thing
for my otherwise unused 42 tooth sprocket.

Gas or electric makes little difference to the design, they are both a
spinning shaft. Just depends on your personal preference. The benefit to
gas is much longer travel. But DeWalt cordless drills now have five amp
hour batteries. Not great, but usable. And it will only get better.

Wow. It's unfortunately not uncommon for civil, helpful posts to get
labeled as trolling; but I think Mr. Doe just set a couple different records.

Mr. Doe, you now have an opportunity to build your contraption and prove to
us that you know more than 1/100th of what Andrew Muzi knows.

Good luck. You'll need it.

I have installed various gas and electric systems for
customers and have wrangled with general formatting issues.

The motivated users are frequently victims of nerve damage
or other injury/frailty/decrepitude such that a constantly
engaged powered drive chain would have been a serious
hazard. Even for a normal human, I would refuse to set up
such a thing.

One project for a woman with MS concluded with a
rack-mounted small motor driving the left side of a double
sided hub with a reverse freewheel and full chain case.
Quite a lot of fabrication but it suited her needs. YMMV.

Since the vehicle becomes unwieldy for carrying up stairs
anyway, I think most of these projects are less useful and
more expensive than a small moped, but people have their own
views.

True, although the Whizzer used a bolt on pulley on the rear wheel
which is a much simpler modification then fitting extra sprockets to
the pedals.

could also hurt yourself while "exercising" or "popping the top on a

Not really a desirable thing to do; going up hill :-)

I wasn't suggesting a gasoline engine, I was simply offering an
alternate design for powering a bicycle.

Are you sure about 5 amp hours? the DCD 980M2 seems to be listed with
a 3 AH battery, which depending on how it is rated may not be enough
for more then very short rides.

The DCD 980M2, for example is stated to produce 535 UWO so would
require something in the neighborhood of 26-3/4 amps at full rated
battery voltage (20 VDC) so a 5 WH battery would theoretically last,
what, 11 Minutes? But only if the battery was capable of producing
full rated voltage at maximum current draw.
