Not that I know of. The limit will be battery, primarily. The motor is 2kW, so that is approaching the upper speed limit caused by wind resistence. The cut-off is for legal DMV, DOT registration purposes. When you go over 28mph, the software only kills power when you run out of battery or will overheat.
I am beginning to like this bike. It has a beautiful belt drive. It has plenty of torque, and appears to go pretty fast. They call it an e-bike on their website. Here is a quote directly from their site. "The Grace ONE.15, with stunning technology and perfect design, moves up a level to a new dimension of riding pleasure: purism in perfection. Powered by a performance that sets new standards for an E-bike and gets the adrenaline pumping."

I love the design of the bike. I really have to pinch myself. The motor is made in India by Ultra Motors. The Motor seems to have low performance. The elegant design and Ultra motor seem like a mismatch. I think the motor is OK, but not on the same scale as the rest of the bike. That bothers me. It seems like they are cutting corners. I do not know for sure, though.

In your case, the Pinion is a gearbox with 500% gear ratio for hills. Pinion comes from Porsche engineers.

But the motor has lots of torque and watts, what is low performance about it? the durability?

The distance the battery travels. Maybe the entire system is poorly opimtized? Or, the battery chemistry is poorly matched to motor power. Sometimes, software or the lack of a sensor is the reason.

Unclear to me. The important thing is to list the 10 most important benefits to you. Compare against risks and costs. Nothing is perfect, just need to make the best tradeoffs.

Gear ratios are important to me. Pinion is the best solution. I like the belt, too. You cannot have everything.

I guess a general question is how roadworthy is the bike? You cannot beat a bike built to DOT standards. The fact the bike has a horn and lights is revealing.

On the downside, high speeds require a suspension. Hitting bumps at 25-35mph is jarring. I am very surprised Grace omitted regenerative charging.

Yes, but remember the old days when suspension wasn't around? I use to go all over the mountain with a bike with no suspension. Even though they have neglected to add suspension, it still could be a very good ride. It may be more stable than a suspension bike at those speeds. Ok so what's your opinion. Full suspension haibike, or grace one.15

Tires act like shock absorbers, so you get some help. But the bike is very heavy at 70 pounds. Most of the weight over 1000W is due to the beefy frame, motor and battery. A rack is important to carry food from the store. Full suspensions do not like racks.

I guess it mostly depends on your route. If the road is smooth, the Grace is better. My legs are the best shock absorbers. I would stand up and absorb the hit with my legs, anyway.

Bosch motors lock up in mud due to the small sprocket. You would never catch me on a full suspension Bosch .

I have to go with the Grace. But it does not mean I would buy it. I think HPC also deserves consideration. The main reason is the battery.

ok! I have eliminated focus and haibike. I feel as if both of them just mount the battery on and the motor. there is no custom design or anything. seems pretty rushed to me. haibike may be good, but they just appear to be normal bikes with additions. Now I must compare the Grace to the Stromer st2 and the stealth to hpc to optibike. these three brands all boast high power and full suspension

Just read this article I wrote. If you google for "electric bike motorcycle cost benefit" it is the #1 Google search result. Please remember to like the posts that help you. Otherwise, I do not get enough feedback on what people find useful.
 
You don't even own an ebike and have never ridden one yet you spout hundreds of posts with advice like this:

This only applies to real mountain bikers in extreme conditions in which 99%of riders never get into.

I agree to the point in which I wouldn't take an e bike into the mud. For the cost places on an electric bike, it seems somewhat unclear why someone would cover it in mud. unless you live in a tropical region and it begins raining on your trail, but that's an extreme exception.

I live in a suburbia. I love my 44 acre park that is very muddy and rutted after rain. The hill is a 10% grade through a steep canyon. I guess I should stay out of the park when it is muddy. I just love the park. I track the mountain lion and her cub. She has a name "Silverhill". I can only track her after rain.
 
So the Stromer has less torque and a lower top speed, but it has wireless comparability with the iphone. there is a compromise on both ends I guess, but at the end of the day performance is the most important. Also, optibike has been around forever, and they have made a custom frame design to center the weight over the middle. they might have a slight lead over stealth bikes, and I would place hpc last. anyone have any other thoughts? I am starting to feel less overwhelmed by the market. :)

Are you in favor of Bosch drives?

that sort of terrain sounds more for an atv or Zeromotorcycles

I took a look at OptiBike. I could not determine the battery chemisty. NMC battery chemisty is at least twice the performance of any other li-ion. It should also be half the cost in the future. The chemicals are cheap. Ask optibike about their chemistry. You really need a good battery for your purposes. ZERO motocycles switched to NMC. most of the EV cars use NMC.

Here is how i see OptiBike M7

Optibike and Stromer are same problem no battery chemistry! What are they hiding? I like Stromer battery better than Optibike, but I cannot tell! That really pisses me off!

48 volt / 17 ah / 814 wh Lithium-ion cells by Samsung

For a 120 pound rider, I put Stromer over OptiBike, HPC and Stealth Fighter. Stealth seems like overkill.

I think Grace One.15 and Stromer are roughly equal. In your case, I give the edge to Stromer.

If you want a front suspension, then I would choose the Grace One.

You also might want to look into the Grace One Pro, which gives you better gearing with SRAM X0. I still do not know the exact percent grade on your hill.

I see your point, but I highly doubt that optibike uses low performance batteries. Optibike has won numerous bike races, and everything is built from the ground up. I believe it is safe to assume that they use a good chemistry. It is clear to see where stealth is coming from. they are making a powerful, fun "race bike" that will do pretty much anything. I am looking into the grace one.15. http://electricbikereview.com/commu...5-will-not-be-available-in-usa-for-2015.1528/
I looked at the Stromer in the store today, and it was quite elegant. I just didn't get that "excitement" feeling that I get when I see a stealth bike or Lamborghini for example. Hpc is really a mystery. They have no customers posting videos on them, and a lot of bad rep about posting false specs. yet they have been around for a really long time. That seems like a gamble that I'm not willing to take

not in particular, but I do think there are many bikes with Bosh drive that are excellent and that I would not hesitate to buy.
