Hardcore has it right. I would add, get the largest battery available. Otherwise stay with the base components.

HT or FS is a personal choice. My wife ride the AM1000, I ride the HT 1000.

I can tell you the HT 1000 frame is very strong. I am running 3000 watts thru it with 60 volt batt at 50 amps. Rock solid at 43mph...…

Thanks for the replies Hardcore & garyal1. I ended up opting for the Biktrix Juggernaut Ultra 1000 48v 21ah. Going with Frey would've saved me $600 landed (2800 vs 3400) but the customer service from Roshan at Biktrix gave me peace of mind. I also ended up with a hardtail instead because of the cheaper cost and lighter weight. I have to say though, I almost went with a Luna bike since the price point was much lower and the luna ludicrous 2500 watt on a mid drive was very enticing but the Bafang Ultra was a requirement I wasn't willing to compromise on and I believe that the only ultra they have is the apex/apollo.

Hey Lefre,

You will not go wrong with Roshan / Biktrix. I do not have a Biktrix model, because I was not educated enough when I first bought my two "Addmotor" bikes off Amazon. If I had been, they would have been Biktrix models with better features, I did buy a 21AH battery and some other accessories thru Roshan and was very happy. They also get great reviews by customer here and elsewhere.

As for the Apex, you can search this site for my experiences with that company. :(

That Juggernaut is really going to amaze you. I think they ship with 30 amps enabled, but I would highly recommend buying the programing cable so you can fine tune it and make it your own.

What size wheels did you choose as they have options...

One other benefit you forgot to mention is the almost instant delivery thru Biktrix.......I am sure this helped sway your decision! :mrgreen:

Garyal1, I'm glad Roshan is talked about in such high regard by many. I emailed him asking if he could help me out a little more with the pre-order for ultra fs and he humored my request. I thought it really said something about his customer service for even considering it. Understandably he couldn't do it for the hardtail but my faith in him and his company was set in stone after that.

I went with the 27.5 x 3 tires because I'm not a big fan of the fat tire look, I may end up switching them to something smaller after I receive the bike. I've never ridden a fat bike though and hear it's a different beast on the trails/sand.

Haha yes, one of the things that definitely solidified my choice was that he has stock in NA and it wouldn't take 30 days+ to receive it. I'm also glad that he partnered with a financing company. I can ride my new bike while trying to sell my "old" ones.One is a 2 year old 250 watt generic road bike and the other is a fairly new one that I bought roughly in February. Unfortunately the latest bike (EEB frame) is too big and heavy for me and it doesn't fit in the trunk of my suv. It's a hell of a monster that clocks in at 50 mph though! Wish I could take it places farther than a 20 mile radius from home but pedaling a 120lb bike on hills doesn't sound too appealing.

I'm afraid I'll miss having all that speed and power but I'd much rather have a lighter bike with better weight distribution and range. The hub motor on the eeb gives me massive anxiety when I'm going up steep hills in fear that I'll burn it out :lol:

I'm excited to get on my new bike! I have a Luna bbs02 on a kona splice (that I gave to my friend when I got my eeb) and I imagine the juggernaut will feel similar to that but with more torque (correct me if I'm wrong lol).

What's your current set up?

Edit: I forgot where I read this but I think it said something along the lines of, "throttle only works on pas 5 and does not work at all at 0" if this is the case, can it be bypassed with a programming cable?

Just wanted to see if anybody had any suggestions. The motor on my AM1000 quit while I was riding it on fairly level ground and on a fairly cool day. The display powers on and shows no error messages and the battery is fully charged. The display shows it is putting out about 500 watts but no power to the crank. There are about 200 miles on the odometer. It could be an internal gear issue but unable to determine without taking the cover off and It appears that the mounting bolts were over-torqued at the factory. The LBS was unable to loosen the mounting bolts as well.

The long ones that attach the motor to the mounting shell on the chain side. I'm using a 5mm allen wrench. I may try an impact socket if I can find the right adaptor. There's nut on the other side of the bolts.

Are you able to remove the nuts on the other side of the long ones?

From my memory of opening it, there was just the removal of the bolts and I could freely remove the long bolts. There was no torque on them. But okay, let me know what you did to open it.

I just recently installed one of these in a new frame. I have also pulled and installed several of these in the past. Once the nuts are removed from the non chain (left) side, then the bolts just need to be driven out with a hammer and drift punch. I use a 1/4 brass shaft as my punch to make sure I do not damage the bolts upon removal.

Be sure to support the unit if the wiring is still connected. Otherwise it will drop and pull out the wires. Don't ask me how I know this! :mrgreen:

Hey owners, which size frame for the AM100 and how tall are you? Did it fit you as expected, or did you think a smaller or larger frame would have been better?

Thanks, I just watched a YouTube video by Backcountry ebikes on how to remove the motor that said the same thing.

I would also be interested in hearing about this. I am just over 6'2" tall and I ordered an XL as per Ivy's advice.

So, let's hear it

6'4" and I got the Large frame (not XL). Reason being that L looked big enough, and if I got an XL I figured nobody else would be able to ride it. It turned out fine.

5'10'' (178 cm) and I got the M frame size (short ST + 150 mm dropper), very nimble size for me. I do have the seat all the way back and didn't cut the handlebars.

About warranty claims:
I recently broke a tooth of the 48T from my SRAM EX1 groupset, Frey/Ivy had me contact the SRAM S & S for warranty, which was all fine and they'd replace it but apparently, it has to go through the seller. Hence, I had to send the cassette back to China (60 bucks) and been without the bike for a month as it just arrived in China. Hopefully, they figure out how the warranty claims will work smoothly as also other components might need warranty claims. Not even to mention if something is wrong with the suspension. So I have just been going through some old footage and uploaded some to youtube. It seems I cannot find many people posting themselves riding the ultra bikes.

I have a Hunter model on order. Delayed 2 months due to rockshox fork not in stock. If you order one make sure shipment is ddp not dap. I order mine thru hangzhou newline tech, sales person Jerry Fang. Hangzhou Newline (Cinline Bikes)is in the same factory as Frey and the same bikes. This is according to Ivy, which is selling bikes as the Frey brand. Im going thru Alibaba. When using Aliba keep in mind chats are saved indifeniely on cell phone, but only stored for 7 days on computer. I suggest only using the Message system, not Chat on Alibaba if using computer in order to retain all communications with sales people. Paid asking price with fenders and front light added. Shipping 800 DDP method. Rockshox $135 additional over standard shock.
Hi Chulen,
did you get the bike yet?
what are the pros and cons?

I got the motor out of the frame but still trying to get the nut off as shown in the attached photo. The silver one that says 35 N.M.

Yes, It's a reverse thread and I may have over tightened it counterclockwise with vicegrips.

Thanks. That might work except it freewheels when I turn it clockwise. I may have to reinstall the chainring and see if that helps I guess.

Finally the weather is good enough to test my ebike which has a Bafang Ultra 1000W. I want to check out if anyone else has the same issues. The torque sensoring isn't working as I expected, it is very jerky, even if I pedal at the same rate the motor will turn off and on, shouldn't it be smooth?

It all depends on how it was programed.
The Pedal assist is a mixture of torque and cadence sensing.

The torque sensing is the most natural way to provide power assist as it is proportional to your effort, but could lead to what you describe, in situations like pedaling on flat, when your effort may fluctuate between zero and some, causing the assist to be on and off.
For that reason, the pedal assist also combines input from a cadence sensor, to try and smooth things out in this kind of situation.

How both are blended is a complicated thing that is done with the programming of the assist.

Depending who provided the Motor and programmed it could influence the quality of the experience.
