Electric bikes

Nine speed de railer on the rear tire. So I have 9 speeds. And 4 levels of assist or just throttle
If the bike is moving about 1 mph you can use the throttle and you do not have to peddle if you do that your battery range will only be a few miles
If you peddle and use level one assist they claim 60 miles. I think if is flat and you weigh 150 pounds that is true. For me 40 miles in flat terrain paved roads and peddling

When I get home tonight I will take a picture of the rear hub

So your motor is not using those gears, you are using those gears when you pedal, right? Your motor simply assists you pedaling and your gears only make a difference when you are pedaling?

If the motor is at the bottom bracket then the motor drives the front sprocket. If the motor drives the front sprocket then you can use all the gears with the. motor whether you pedal to assist or not.

Do I have this right or am I not understanding what you have?

From what I gained when reading and watching everything I could on the subject, is these motors can and will burn up if you abuse them.
Hills are the main form of "abuse" if the motor isn't spinning fast...its not good for them to bog down. Its why being able to change into those granny gears with a middrive and allow the motor to keep spinning fast while slowly taking you up is the smartest option.

Still if you have a good warranty with a prebuilt hubmotor bike, whats the risk?

I do know you can order internal parts to fully rebuild your bafang middrives if necessary...probably can do the same with the hub motors if you didn't have a warranty

right, the motor isn't using the chain to power the wheel, so those gears you see aren't doing anything except from pedal power.
Its possible there is some kind of internal auto gearing though, dont know enough about them

My bike with an old thread injector in the back

As far as reliability
I know a guy that put 40000 km on his bike going to and from work. Only repairs tires brakes and a new battery after 40000km

I have never seen a warning on this bike about burning out the motor on a hill

Gearing down going up hill and pedalling would probably be fine.

Bionic has a new motor that is belt driven and no gears It is an option on the elby bike.

My wife’s new elby bike with the same motor. Supposed to have a 120 km range. With her on it on paved roads flat terrain level one assist probably

I’m not concerned about the warranty. I’m concerned about whether or not it has enough power to make it up really steep hill with me loaded down with gear. I will be riding it purely off road. So there will not be grades designed for cars to travel on. There is going to be some pretty steep, rough, grades that I currently cannot pedal up with all my gear loaded on, and pushing the bike up these hills with all my gear isn’t an option either. I’m better off just walking if the bike can’t get me up. If you have the choice of putting the bike in a low gear and the motor still running at top RPMs then it should be able to climb almost anything. This is what you do have with a mid-drive motor.

I need to do more research. I could have sworn the Rad Rover bikes switched gears. Maybe not.

Do switch gears they have 7 gears and pedal assist and the 2017 models are the ones that were on sale for $1,200. My friend got a white one I don't know if he could have got a black one or not but for 1200 it's a deal
 
If you want to try a hub kit and have an old bike laying around there are some cheap diy kits on amazon and ebay...under $150

you just need to come up with a battery to power it.

The manual on the bionix system has no warnings about burning out the motor but has warnings about maximizing battery distance. You use your shifters to maximize your pedalling distance It says shift like you would in any other bike.

the gear cassette only works from power imparted by the chain though. It switches gears, but the only benefit those gears have is from the force of you pedaling

Bionix may make their own motors. My statement was about basically everything else outside of the newer mid-drives being put out by bosch and some other big name mountain bike companies. Just about everything is Chinese, especially anything cheap. The Chinese stuff is all pretty much the same in quality. I'm not trying to downplay anybody's stuff, just trying to pass on what Ive read about

No problem. I just like the bike. I am no expert but I do know Magna International who own Bionix does a lot of outsourcing to China but their standards are very very high. So yes you probably are correct.
I had a bike shop owner say that the electronics in some Chinese made bikes vary from shipment to shipment and are impossible to fix.
The motors do come from here though.

Okay this will explain exactly what I was asking and concerned about. The hill this guy is attempting to climb is weak compared to what I need to climb.

Another one
