I had the same trouble with my square taper puller. It worked for my 2008 Giant Alias but not this bike. While the tool threads on to the crank fine, you can see in Ivanovitch's photo above the ISIS has a much larger inner diameter. The centre of the puller just slips right inside with nothing to lever against.
There is a separate larger diameter tip for the puller, that fits the bigger bore ISIS shafts.
You could improvise one from a suitable thick washer or similar..

Yes it does but, ... That tool is for removing the whole BB bearing cassette...not the cranks from the shaft.

My bad sorry. I am using the same crank tool for both my square taper and isis bb. The round piece at the end of tool is very important for isis bb

Yes its important..as you have discovered it doesnt work without it !
But it is only a metal "plug" of the correct dia to fit inside the crank splines and rest against the shaft shoulder.
As i said its possible to make one, ...no big deal.
...but the correct "universal "tool is only $20 new !

One could also buy self extracting isis bolts (in the tool less variant) instead of a compatible puller. I don’t know if they work with standard isis cranks tho...

I have the SRAM EX-1 isis crankset and they come with these. You only need an 8mm hex bit for both install & removal :D !

Paikan. I have a bad news.

They called for me from my local ebike store and told that my bike back frame is bent about 0,5cm :( So that is the maybe reason why my bike keeps that noise. Also it could be good idea to check your bike rear axle and drop out threads from the inside because mine drop out was taken little bit damage. And because that back frame is bent about 0,5cm was that axle also little bit tight when I tried to take it out. I am going to send that report to Ivy so let's see what happens next.
Hi Mantsos:
The noise only appears when the motor is working at high amperage rates. When the motor is off, there is no sound, so yesterday I try not force the motor monitoring watts in screen, and and the sound was louder...

By the way, I´m going to check rear axle...but i d´ont know how check that 0,5 cm of the rear frame :(

DISASTER: 40km from home, 95 in the shade

My biggest fear about ordering this bike was what happens if something really major goes wrong.

Today, 40km from home it did all go wrong. The power delivery suddenly became really juddery, followed shortly after by a horrible noise from the motor, and then I lost all power. I could hear the motor turning, but no propulsion.

I had to cycle a 30kg bike 40km in 95 degrees to get home. Pretty brutal.

I wanted to make a quick video to show what's happening, but now it won't even switch on. To say I'm gutted doesn't come close :(

I have ridden my AM1000 almost every day since I got it 4 months ago, and have loved it. It's done 800 miles, and I keep on top of basic maintenance such as checking for loose nuts and bolts, cleaning chain, adjusting gear cable etc.

My riding is not aggressive, usually between level 1 and 3 (sport mode). Off-Road 40% On-Road 60%.

It's lovingly cleaned whenever I've been off-road and I stick to the easy stuff with nothing too taxing. The bike has had an easy life so far.

I ordered the bike in February 2018 and was told it has the steel gear, not the nylon, but it does feel motor gear related.

I'm REALLY hoping that Frey do not abandon me, that they take this seriously and get it sorted ASAP. I've just sent Ivy an email to explain and ask her what she needs from me to get my bike fixed under the warranty. Any which way, it looks like it's going to be as while before I'm back in the saddle :(

The thought of taking apart the motor to replace gears fills me with dread.

Anyone any ideas what could have gone wrong?
Ivy has asked me to remove the motor and return it to China, but I'm having problems removing the retaining bolts holding the motor in place.
I’m having problems removing the retaining bolts.

I have tried 2 approaches:

Removed the lock nut on the right side, then tried to unscrew the Allen nut on the left side. The whole retaining bolt just rotates and nothing happens

Then I replaced the lock nut on the right side and tried to undo the Allen nut on the left side, but it absolutely will not move. If I apply anymore force I will break or strip the Allen key.

Can anyone help?

Thanks

Dan

Take the nuts off and belt the bolts out with a hammer and a steel rod (I used an old T30 torx screwdriver). Seriously. They aren't threaded, just really tight. By using a rod centred on the bolt you are less likely to roll over the thread with the hammer.

Brilliant. Thanks Tom. I'll grit my teeth and give it a whack :shock:

Update: Done it :D It's hard to apply violence if you're not sure it's the right move.

you can use luna wrench or the bottom bracket shimano TL-FCsomething tool (beware, there are different Ø that look almost the same).

Wow - great job getting it home - I would have called a tow truck! Keep us posted! I don't have mine yet, should be getting close to completion. I am riding a Rad Rover now, really looking forward to trying the AM. I will say the RAD has been an amazing bike thus far, this will be even better.

Thanks Ivanovich_k.
I took the motor into my local bike shop, and after the staff member picked up his jaw at the size, weight and power of the motor (he's used to Bosch and Yamaha 250w power plants), he came up with the correct tool.
I want to give the size and details, but nowhere on the packaging does it give any sizing details.

If the lockring is 16 notch, 48.5mm, then the Park BBT-29 should work. The BBT-9 will not work. The Luna Bafang tool will work (I just measured it). The Shimano TL-FC36 tool... maybe?

That's cool that they had one with a nice handle; with the double-sided ones or the Luna tool, you're stuck with a thin metal edge to grip.

Ouch! They are looking at tariffs on them for US as well.

I just got notified that the EX-1 set will not be available until sometime in August, Ivy and team will ship the bike as is with the standard set and then ship that later. Looking forward to getting the bike! I have a Rad Rover and a mini now that I really enjoy, can't wait to try the AM1000!

Hello,
also bought a Frey AM1000 one month ago - and still love it. it is really a cool bike...

concerning the battery lock:
i dont think that a longer bolt will solve the problem because the hole in the battery would have to be deeper which is not the case i think.
but i recognized that the bolt of the lock was adjusted. it is not curved at the end anymore. i think this little adjustment might prevent unwanted openings or am i wrong ?

... can anyone suggest an appropriate LED light (front/rear) for this bike, that is removable for the trails?

How is everyone finding their AM1000? Still not too many reviews/videos on it.

I think if send by express, there is little effect on the tariffs change in Europe. we have some bikes go to Europe recently, no change on tariffs, as express company handle the process in a simple way, not very strictly.

Hi All,

I have been riding my am1000 for about 400km now over the past two months loving and hating it.
In the meantime, I've had my share of problems as well. All in all I love the bike, but so far this has happened chronologically:
1) gear sensor was not installed as requested - one was send to me for me to install
2) battery fell out of the holder when the top plastic part broke (after I warned them 1 or 2 screws is not enough to hold it in place) - new top part was send to me with a longer locking pin, damage to the housing of the battery is minor but doesn't look new anymore.
3) rear suspension broke, one of the rods broke in half - new one was send to me with new bearings
4) kickstand broke off - replacement bolts were given
5) chainlength was not adjusted for the sram ex1 cassette - new one was send
6) novatec freewheel hub snapped in half - compensation to buy my own rear wheel
7) rear axle snapped in half - replacement was send
8) the left brake lever snapped during a fall (not even a serious crash) - bought a new set myself

But on the other side of things, this system is capable of 45-50km/h top speed for ~30km. If avg is 30km/h you get about 40km range (with 850 height meters). I have two 52v batteries that can take me for a collective 4h cycle ride covering about 80km and 1.7km in height (human pedalling included). On sram's ex1 biggest gear it can climb the steepest hills (30-45%) if you can keep your balance and traction. Anything that is steeper will throw you backwards. I do have a dropper post installed but had to forcefully clamp it because the diameter was slightly larger than 31.9mm as advertised.

More details about the bike:
Lyrik 160mm front fork
Deluxe RL rear suspension
SRAM ex1 upgrade
203mm rotors front and back
front pads upgraded to magura MT7 race variant (they are compatible)
150mm dropper seatpost internally routed
first trips were done with the original wheels (rekon 2.8+) but switched to minion DHF 2.5 and DHR II 2.4 WT version and DH casing in the rear.
52v 17.5ah battery and limited the controller to 25Amps

new parts are:
DT swiss H 1900 35 mm
Robert axle project replacement rear thru axle

That is a frightening list, on the first read through for only 400km traveled. Are you trail riding or where these on road incidents?
