    I've never heard of such a small motor putting that amount of speed and torque without some funky gearing. I can't seem to find any unusual ratios in the sprocket setup they are using. also, to accelerate the bike you are going to peddle as well as shift gears since it is a mid drive. This is...

    yeah, fact is that your legs can't start spinning fast enough to get the motor to gun it. I think that is the way they get a bit of range. they can gently accelerate to reduce power consumption, and they also have your legs assisting the motor. yet they have so much freaking torque.

    so you think that their battery won't be able to discharge fast enough and the motor won't consume enough to give it a lot of power. yet it has lots of torque and a high top speed since the power doesn't get sucked as quickly

    yes. I with the spitzing had a throttle. that's my only sadness. the acceleration can't be bad when you look at how fast he popped a wheelie

    How would the M1 compare to a scooter with a 750 watt motor and a 15/76 gear setup. it has 24 volts, 33 amp hours, lithium ion batteries, and goes 20 mph for 26 miles

    hahaha I listened too. quite quiet. It was amazing how easily he did the wheelie. Id imagine getting to at least 35 is no problem.

    Yes. I was quite shocked when I saw the specs of the M1

    It is quite sad though since I did love the stealth fighter. Made in Australia was quite appealing to me, but Germany just is amazing with mechanics. I'm still looking at the grace. would the M1 be loud since its a mid drive

    That makes more sense. It's a very inefficient motor, so therefor the performance comes at a price. Meaning that if I went on a trail, I'd burn through the battery very quickly

    only one. Then how does the stealth have so fast acceleration??

    how does the stealth fighter lose again? it doesn't have as many volts?

    Optibike M7 or R8

    I like that bike, just doesn't have enough power for me haha

    The grace could possibly handle off-road. I'm awaiting an email reply from them

    M1- Fastest, Most Torque, Fairly exciting top speed, off-road capability, lightweight carbon frame, distance Stealth-Fastest acceleration, most solid frame, off-road capability, very exciting, decent top speed Grace-pinion drive, belt instead of chain, good price, high quality

    That would put stealth at the most exciting, but the M1 would be exciting on the top speed.

    True, but you can't really take it on the trails, which would be the most exciting part

    the purpose for the M1 seems to be all around. the grace seems for road. and the stealth seems for off-road

    Need help with Haibike, M1 spitzing, stealth, optibike, Stromer,focus, or grace e bikes

    Alright. so let's look at this. M1: Fastest top speed Most torque Longest range Grace: pinion drive stealth: fastest acceleration most solid what do you think? anything else to add on?

    Do you think that the stealth or grace runs over 48 volts
