Got an update on my torque issue.
Sent down the motor to Bafang in Netherlands and they found out that the torque sensor was broken. And they will send a new motor as a replacement.

Thank you for the help when looking for the issue. I hope to experience the bike as it should be!

Just about to pull the pin on this bad boy! I read this whole topic top to bottom and tried to pull all the best bits in to my spec. The only thing not there is the improved thumb throttle but Grace @Frey said they can only supply the standard one. She's been really responsive to all my questions too!

I'm paying extra for the gear sensor, for the motor. Is the gear sensor necessary do you think and/or should it really be standard?

I'm also going for an extra battery. What are the chances of improving tech meaning that a higher ah 52V will come out soon and is there a risk that if I only bought one and something went wrong with it wouldn't be able to get another, or would have to get one made bespoke? That could be a whole world of pain. I've actually gone for the 48V 21ah rather than the 52V 17.5ah owing to the greater energy density (should get better range but perhaps lesser top speed and ultimate performance, right?).

I'm based in the United Kingdom by the way - not sure how many others in the UK have bought a Frey AM1000 yet - if local to me I wouldn't mind having a look. I'm in Sussex near Gatwick.

I think the gear sensor is a must have for the high torque motor, the extra cost is minimal.

Nice list!
I am also thinking about to buy one and read the topic top - bottom.
How do you choose the size? How tall are you? Why no SRAM ex1 on the list? I read a lot of good things about it.

I live in EU and the only thing that is holding me back is customs...

I gave my height & weight to Grace and she suggested the Medium. I then looked up all the geometries for the medium and checked it all against my existing Yoeleo M91 Hard tail MTB which fits me like a glove. Pretty much exact same apart from the chain stays that are a bit longer. Anything bigger than the Medium looks seriously huge! I’m 5’ 8”.

I think ex1 is quite a lot more and Shimano M8000 is very good kit already.

I bought my Yoeleo MTB direct from China (frame and wheels only and I made the bike up) and had a very good experience. I’d also had another set of deep section rims off them for my road bike and it was very nice quality.

I do a lot of cycling and love anything that’s got wheels on it!

Also with the SRAM ex1 you’ve only got 8 ratios so you loose the close ratio-ness of the drive (XT is 11 speed). Range is the same but each gear change is a more significant jump in gear ratio. For me as big cyclist already I like to cycle with a fairly high optimal cadence (90-ish). Probably less of a factor with a motor but hey ho!

Yep. Order placed today. They’re waiting on a new batch of the Rockshox Lyric forks to come in but should be with me by end May

Does anyone have any input on the charger that comes with the Frey bike, I'm talking about the 54.6V 5A Smart Charger for the AM and HT 1000s. What makes it 'smart?'

Nice, I still have doubts about the battery voltage...can someone help me here :-) what are the cons at 52v?

48v battery is about 10% more Wh and about 8% less max. power. But in my experience, the 52v will give you less voltage drop under high load and more consistent power 'feel' throughout the full use of the pack.

Hello, I ordered a Top of the line Frey 1000 watt duel suspension bike. My original reason for buying it was to commute to work. When it came I realized that it was too big of a bike for my to keep in my office. I would like to sell it, please email me if you are interested. It has 20 miles on it.

Are there battery readout problems on the Bafang screen, can it handle 52v? Less voltage drop sound like a more pleasant ride.
I going to buy 2 batteries so 10% less Wh isn't a problem.

Where do you live, whats frame size and how much do you ask?

Hello,

Here we would like to share with all you how to use the gear set better.
11速飞轮与链条最佳使用指南.jpg
Best condition use guide for 11 speed cassette and chain.

Green: best starting and riding level. The cassette and chain life is longest, and riding effect is the best.
Blue/Yellow/Red: under the speed showed in the graphic, cassette and chain is in the best condition, minimal wear.
Color meaning: Risk level of cassette and chain.

How about your use tips? you can share with us!

no problems reading the voltage on the screen and yes it is a pleasant ride. I have another 48v hub and I can certainly feel the battery reaching LVC while the 52v on the frey keeps more power till LVC

cheers

I was having the same dilemma but opted for two of the 48V21ah batteries with my AM1000. Surely you’ll have less potential peak power with them but a longer burn given the fact that they’ve got 14% more capacity in the first place (48x21=1,008 WHr vs 52x17=884). Whilst the voltage on the 52 is obviously higher than the 48 it will drop faster at the same drain level.

....or have I got this all wrong and I should also change for the 52V17ah.

Are you about to order an AM1000 Razerr?

Yes i do, pretty close to make the order.
a friend of mine rides a BBSHD and also mentioned the fast drop of power with the 48v, the voltage drop was a lot smoother when he swapped to a 52v battery. Yeah you got more miles with the 21ah but still plenty miles with double 52v 17ah batteries...

It is a difficult choice because more miles per battery is attractive, but the way the battery behaves when discharging makes for a better ride. I guess..

I’ve already placed my order with Frey and paid for the AM1000 with two 48V21ah batteries but I have asked whether I can switch to two 52V17ah batteries instead, obviously with the correct charger for the 52V pack. I’ll let you know how I get on. It is a difficult one and I guess six of one and half a dozen of the other in terms of weighing it up. Thanks.

Now the frame size. I am 5.9 feet (+-181cm) I was thinking of the large variant.

I would like some opinions of the frey bike owners.

Go with the medium frame size if you're 5'9" tall, you will regret it if you don't.

I would go with the 52v batteries, its worth the extra cost. I don't think FREY will have any problems upgrading your order, I went through the same thing making battery decisions.

181cm is 5'11" i think.

You are correct, 181 cm is 5'11". I'm 5'9" and the medium works great for me. If the medium was any larger it would be too big for me.
Maybe another AM1000 owner will chime in on this post for you.
