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, the SpitoI
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
you might want to try find an acceleration chart for Spitzing. I think their battery is designed for distance, not power. The Spitzing range is something like 120 miles! It will reach high speeds, but you will not get a big rush from gassing it. The Grace may accelerate faster because it has a throttle and 2000W hub motor. I cannot find Grace 0-30 speed.

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
 
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.

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 starting to sound a little impractical and weird.

Good one, Kyle! I think the Grace blasts out of the starting gate, but starts to fade later on. Spitzing is like a Ducati. Grace is like BMW motorcycles.

Yes, that is very German style. Does prevent the motor from burning out.

Well. I may not be super good at numbers and conversions, but I certainly see something weird going on. How can that amount of torque be accomplished while maintaining such a high speed with such a small motor. Either there are some intense gear reductions, or the acceleration may be terrible. When you look at grace, they don't have the fastest bike, but they appear to have reasonable torque and acceleration. They probably has some ultra-fit biker perform the hill climb test and the 0-30 speed test. Do you agree?

You have convinced me to go with Grace.

The motor will only burn out if they are using a lot of power in a super small motor. Usually, if you use a motor with more than enough power, it won't burn out since it isn't working too hard. if you squeeze everything a small motor can give, you will be producing some heat

Absolutely ! Spitzing is like a single cylinder 300cc grunt motorcyle tons of torque, but you cannot burn rubber.

You got it! Seems to be like a tractor in motorcycle form. this may prove to be good for people with tons of straight roads, but I know I'm not going to peddle up to 45 and immediately slow down on a bend. that would be crazy!!
 
I'm just quite afraid with the numbers I am seeing. think about this too, the bike is super light with those specs. Carbon fiber will save a few pounds, but nothing that substantial.
Yes, the Spitzing is too torquey. Who the climbs a 70% grade? Only a freaking mountain lion.

It's quite sad since I saw a lot of potential. imagine a bike that could accelerate 0-45 within 6 seconds, and had a twist throttle. it maybe has eh 55-65 nm of torque. When I first saw the bike I believed it was the case, but it seems that we have cracked the code!! It's clear that stealth still holds their little throne in the e bike industry still. with a nice companion being grace, and Stromer tagging along behind them

one time a mountain lion pooped on my deck, I couldn't believe what I saw. took me about 5 minutes with the hose to clean it up!! some pretty big cats if you ask me. just be careful. if she has Cubs in the area and you zip around in your bike, she may get protective
 
For me, it still is Grace. You might want to reconsider SF. SF suits you better than me. I will see if SF has a 76V option
Yes. 35 miles per hour on the fighter seems fine. I could imagine how much wind resistance you would achieve already!! the thing that concerns me about stealth is that there are 2 gears. easy and hard. you click the button on the center of the crank. if the battery dies I wonder if it is possible to peddle in easy
 

skip to roughly 2:26. When they are learning how to ride the stealth, look how touchy the throttle is. quite amazing!!!

No way will I ride a bike in the park. I stopped running in the park. She tracked a mountain bike for about a mile. I think she was acting protectively. She does not like the smell of rubber. I just love the park. It is getting too dangerous. Talked with a runner to who confronted Her. She howled like the cat in the car commercial.
