I see you are the official Greyborg dealer but this thread does not have any specifics yet? Can you tell us when the motors are available and exactly what we can purchase?
There will be many different items listed for sale eventually, but the first thing coming up for sale is the Cromotor/Hubzilla/Greyborg motor or whatever you wanna call it. Right now it's the most powerful hub motor you can get for a bicycle. The specifics are not mentioned yet because the time frame isn't exact. I started this thread so people realized that I'm involved with Greyborg so they don't think I'm doing something underhanded and acting as a shill. I'm the first person besides them to get one of these motors up and running and post some solid data and video of it in action as well as my experience. I believe the motors are going to be available mid march. They are currently on the slow boat from China to Croatia where the finishing of them will be done. Once they physically have them here and being the work I will start collecting small deposits to reserve a motor. I'm still lacking an exact final price but I'm in discussions with them (I'm in Zagreb Croatia right now) about the different products and what my costs will be. It looks like I'm going to be able to sell them for $595 + shipping to USA/Canada. I was hoping to sell them for a little less but the first batch is being shipped to me by air freight so we can get them out faster + it's only a small quantity.
After the motors will come frames/shocks/dual front 8 piston brakes/schlumphs/wheels/tires which I don't have the price on yet, but there will be less of the frames available at first.

What it's still unclear for me is the maximum top speed you can get with 100 Volt batteries pack with a 26", 24", and 20"
I can give you estimates on that based on the simulation I've come up with from my limited runs on my bike. It's not going to be exact but this should give you and idea. I really need to go for a slow normal long ride to make sure my shunt calibration is perfect because at the high amp setting I'm running there tends to be quite a few watts wasted in the wiring. As more people get them running or I collect more data I'll try to update my model.
