Everything is closed but atleast you can enjoy the spring and nice weather.

I’ve never been happier owning my FAT1000. This is one of the last forms of sport you can enjoy at the moment which makes it even more nicer.
How is the Fat1000 different from the AM1000 besides the tire size?

I’m surprised your back pack is that muddy with the fenders you have......do you need wider ones?

Those were the ones I wanted to get but having second thoughts now.

Hey Tom, I also wear that backpack out on my other bikes (my home made carbon-framed non-assisted MTB) and its not been properly cleaned. Have no fear those mudhuggers are the business! They work really well, both front and rear. Cheers, Simon.

Chainstay and seatstay width and length are larger to accomodate a bigger rear tire. Otherwise the mainframe is similar with AM1000.

Hello All
I just wanted to publicly thank Ivy and the FREY team for their generosity. I took them up on their offer for some masks. Today I received a very generous supply of masks. I live on Long Island in NY where these masks are in very short supply. I will be putting them to good use.
Again Thank You

Dt Swiss 350 aluminium hub vs. steel hub (sold separately) both after 500kms.

Any of these from the original Frey frame? Or how does it compare?

As you can see the upper aluminium freehub body is severely dented. The 160Nm of torque is too much for it. The outmost 11t cog has almost come loose since it bites the rightmost edge of the body.

If you need to change your rear hub or the whole wheelset switch to DT Swiss 350. It has a modular and interchangeable freehub. A steel freehub body which is sold separately can be installed to it by just pulling the original off.

None of those two are from original Frey frame. I had to replace mine earlier on. The original hub body was looking like on the upper picture although bite-in problem didn’t constitute the failure.

My point is that if you need to replace/upgrade your wheelset a good although an expensive option is DT Swiss 350 hubs. The torque on Bafang Ultra is so massive that it will eventually break the original freehub body.

If $500 is a small amount for you for the knowledge that you’ll never get stranded in the middle of a wilderness due to a failed hub, go for it even if yours is still working!

True, good to know. And thanks for the quick reply. I had about 1000km on my original Frey wheelset, no bite-in at that point.
As an upgrade, I got a set of DT Swiss H 1900 (350 Euro at the time for the whole set), on which I have over 3000km at the moment and no bite-in. I can certainly recommend DT swiss products as a good upgrade.

No probs. You made a good choice!

A Quanta/Novatec rear hub body breaks --> A re-build project of the whole rear wheel at a bikeshop $200-500.
A DT Swiss 350 rear hub body breaks --> Order a new one from ebay. 5 minute DIY project in which only tools required a cassette tool and a chainwip. $50-100

Great thanks for spelling it out.

WRT high torque (160 n.M !)

Does the Ultra get there at low rpm with the stock controller?

think heavy cargo / tandem, on long steep hills

What would a good 3-5K controller be for that besides Nucular 24, ideally true FOC type with motor-temp limiting and variable regen?

If you want to haul a heavy load, a Cyclone 3000 is much more powerful. See that trailer train in my profile pic? Cyclone 3000 :) I tried to pull it using a BBSHD with a 30T chainring to a 42T in the cassette, but it would not pull it up the hill that the Cyclone 3000 had no trouble with. You're not going to regen using a mid drive. The wheel can't turn the motor. It has a freewheel in it.

Waited two weeks for a reply to my purchase query to Frey, so I emailed them again.

Wanted to order an AM1000 to my local port but I have to assume they will only ship to major ports. I did mention my local port in my email, but they seemed to think that was my address. Language barriers I guess so I replied with details of city and state compared to the city they mentioned but again no reply. It's so hard to order it's ridiculous.

They need local dealers in various countries like Sur-Ron has.

Bontrager Hodag’s 27.5x3.8 (really 3.4” on 50mm rims). A great option for FAT1000 as a summer wheelset. I experienced unstableness of steering with a 3.0” wheelset. The tire was just too narrow for a massive hub spacing of 150mm in the front.

Setup may end up with multiple motors

Thanks for the tip wrt Cyclone 3000.

But would still like to know wrt the Ultra (from anyone):

My first email was sent to two of your email addresses - on your website you claim replies in 12 hours. I waited over 2 weeks for a reply to basic questions and only received a reply as I resent that one and got a response.

I sent a second email in regard to your misunderstanding about shipping ports but have not received a response.

I guess business must be too busy to actually care enough to respond. I'm not about to send the second one again. Once bitten, twice shy as I take this lack of communication as an indicator of the level of service I could expect if there are product issues and your lack of timely responses means I will miss out on the special anyway.

Hub spacing has no bearing on the tire’s behavior.

Ok. Thanks for the info. Then it’s the angle of attack of the front fork or something else regarding the geometry.

There was a weird issue with 3” tires on the FAT. No matter of the tire pressure the steering was wobbly and keen to pull in towards grooves of the road and in turns front wheel pulled hard to that side you were leaning or turning. Somehow the geometry didn’t adjust to 3” tires.

Now the situation is completely different. Same rims but de facto 3.4” tires. No problems whatsoever. Behaviour is nice and turning linear.
