One thing is for damn sure when start DRIVING on american roads like the German Autobahn, you better have a motorcycle license. You will get pulled over by cops without a license plate.
Need help with Haibike, M1 spitzing, stealth, optibike, Stromer,focus, or grace e bikes

What did you think of the video. Kinda' trippy, huh? The acceleration most impressed me. Did not feel like a bike ride.

it was awesome! lol

I'm very impressed with it too

Something I anxiously look forward to! A new age is coming.

Possible, but also a possible exaggeration. Electric tech is getting better, but not good enough to eliminate gas

The battery range is a huge shortcoming. Some crazy research happening. Nanotechnology to make batteries. Hydrogen fuel cells for bikes. If electric has a chance, bikes are the most likely breakthrough. Ebikes inspire me. I just wish one company would get it right in the next year.

well, considering current technology, the one.15 is very impressive

The guy seemed to be riding it soft, but he sure could accelerate and go fast when he needed it. This shows how much of an efficient form of transportation this is

optibike uses cobalt battery tech.

I think you need an Internally Geared Hub (IGH) or a gearbox. An IGH like a Rohloff-14 lets you shift without losing momentum. You can even switch gears at a standstill. You need to charge the hill and rapidly downshift. Moreover, you want a motorcycle-downshift-like response that you get by popping the clutch.
The problem with current eBike drivetrains is the motor RPM goes down when you shift gears. The torque sensor deliberately cuts power to avoid mashing gears. The torque sensor approach patches a fundamental flaw that causes cascading side-effects. A gear sensor is actually needed to anticipate the direction you are shifting gears. Impossible for a torque sensor to determine. One of the worst aspects of Bosch -- oblivious to the all-important gear system. In other words, the right hand does not know what the left hand is doing -- dumb!
When downshifting on a steep hill at slow speeds, the motor RPM needs to increase to compensate for the loss of momentum. Polaris Gearshift technology does exactly that with a gear sensor. The controller software is the traffic cop between the battery, motor, drivetrain and sensors. Polaris makes electric cars and traditional motorcycles.

Kyle,
I thought that was very clever of you to take a public opinion poll of the web site for eBike recommendations. Good technique. I should take advantage of the facility when encountering new concepts.

74 pounds is my argument against the Grace One Pro. Sixty pounds is still heavy. Grace need time to drop the weight of the battery and motor.
Due to weight and wind resistence, 1,000 watts is upper limit for an eBike today. Unfortunately, I am looking for a bike to replace my car. I need a 2,000 watt eBike that weighs about 60 pounds. A 1 kW bike can perform well at 25mph. I am actually targeting 20 miles per day at 35mph.

I boiled this discussion to bare essential issues. Cast your opinion in this thread.

I know you will hate to hear this, but the stealth fighter sounds like a good bike for you. It climbs hills like a charm, it can go 20 miles and around 35 miles per hour. it has 2 internal gears. one for pedaling without power and one for pedaling with power, it has a regen button for the hills. But if that isn't your slice of toast, than I think the grace one or the grace one.15 holds its place up at the top! The grace one is a gearless hub motor, so I wouldn't imagine why you would change gears on a hill unless you wanted to pedal. I like optibike, but you need to constantly work the gears up and down to get the most out of that motor. for cheaper, you can get a stealth that is solid as a rock and faster. If I were ever caught in a trail and in a hurry to get home before dark, the stealth would be my greatest companion. also, it comes to California street legal. they limit it to 20 mph at 750 watts. There is a code you can type in to have access to the full power. if you have a motorcycle license i would imagine you could put a license plate on the back, and run it at full power. The grace is s better choose if you are going to want a more bike-looking electric bike, that has a beautiful pinion transmission and belt drive. not to mention how awesome that horn is. it's actually really loud in the reviews of it. I just find the headlight box a little ugly up front.

it would work better if more people voted.
