You ordeting the IGH or the bike? If the bike what is the spec?

WoodlandHills said:There are two different SA 5-speeds, the newer one with the rotary shifter was designed for high torque and ebikes from the start. I used one for a few hundred miles exclusively off-road with no issues until a chain derail broke the plastic shift cable connection at the hub, something that would not have happened on the street IMHO. I only ran 1500w through it but it took it without complaint. I think I will fix it and have it laced into an appropriate rim for my recumbent and replace its Magic Pie with a BBSHD and a Phaserunner/CA3 setup, just to see what happens.
dugg914 said:I'm new at this, but have done a lot of research into ebikes, some of which I believe I may understand. Like others, I would definitely like to have a suitable IGH for my ebike. However, my understanding is that it is European/Asian companies the manufacture the IGHs, and 250W-350W is what their main sales area is limited to. So they really have little incentive to make an IGH that would handle 1500W. Are there any USA manufactures of IGHs? USA seems to be the country for high-powered (albeit illegal for road use) ebikes.

I ordered the bike, got it in black also, upgraded the fork to a Lyrk too and got some derailleur hangers too. Thanks robocam for the color option and hangers (because yes I have broken a few). Guys, Ivy Wang is very helpful and will put up with endless emails to get it right.
Bike specs:AM1000-S.png
Definitely want to keep the bike a class 1 so will be running without a throttle!
Did 12 miles today at a 1500 vertical feet single track before the storm hits. Looking forward to getting it a trying it out.
Anyone know anywhere else to get a programing cable? Luna is out at the moment... maybe will have some when I get the bike.

I dont need so much power and want lighter motor, shorter chainstay, narrow q factor....
Do Frey plan to make bikes with new Bafang motor?
For me I don't see any reason to make the throttle dependent on the pedal assist, if you want to limit how fast the throttle goes, well, use the throttle at the level you need, this is what a throttle doesrobocam said:Just a quick poll.
For the thumb throttle, do people want 100% power to be available regardless of the assist setting, as opposed to having it dependent on the assist level chosen (where full throttle in assist 1 would be lower in power than full throttle in assist 5)?
robocam said:Do you want the thumb throttle to be enabled in assist level 0?
scrambler said:For me I don't see any reason to make the throttle dependent on the pedal assist, if you want to limit how fast the throttle goes, well, use the throttle at the level you need, this is what a throttle doesrobocam said:Just a quick poll.

So my vote is throttle should always map to 100%
The only reason I would want the throttle limited is for different power modes (like street legal and off road) so you are not tempted to go over. This would mostly apply to high powered bike, but given the Ultra is above the street legal power of 350W in Europe and 750W in the US, I would like to see two power modes on the Ultra, for the US, I would want one to be limited at 750W and one unlimited.
robocam said:Do you want the thumb throttle to be enabled in assist level 0?
I don't really understand this distinction because I don't really see the need for assist level zero. I am not getting an E-bike not to use the electric assist, so I have no use for assist level zero.
That said, I don't see any logic in disabling the throttle because the power assit would be off. If you don't want to use the throttle, then don't, no need to have it hardcoded. It is always better to have the choice.
So my vote is also to enable the throttle at pedal assist zero.
Now side question to robocam or others with the bike.
On most bikes using the Bafang (Max or Ultra) The throttle does not work from a dead stop, you have to be going a few miles per hour before it works. This is apparently because Bafang believes throttling from a dead stop may damage the motor.
Can you confirm if the throttle on the Frey works from a dead stop, or only for a few miles per hour, and if so how many.
Note: This mat be different with Ultra using the Metal reduction gear versus the original nylon one

I'm with Scrambler and Robocam, throttle 100% in all modes. Sometimes I actually ride in 0 just for some serious exercise but have gotten caught and was able to throttle up a small steep incline to catch myself.

Ecyclist said:I have Rohloff Speedhub, 14 Speeds on my e-bike and I can tell you that it is worth every penny I paid for it.
You can change gears from 1st to 14th in a second. After a couple of months of riding it became very smooth.
FREYebikes said:...Bafang design the motor not 0 speed to start the throttle because of security and safety consideration under an unexpected sudden start. If want to make the throttle work, must set not 0, it can be a very little number. have you got my meaning?
Robleman said:...reducing weight around 4-5 kg would make it a winning option. Know its not easy...
robocam said:Basically, you can change both values under assist 0 to 1 to enable the throttle in assist 0.
I don't understand the safety issue though. The bike turns on in assist 1. If I don't want it to move, I can turn it off.
