Jean asked me for selection, but I missed this, confused by coil shock

Hi! I want to buy I hardlite axle. For the V1 frame it was 12*1.5 and around 179-180 mm in length

If I have a UDH frame - HardLite SRAM UDH Rear Thru Axle 180mm Boost Super Boost For Eagle AXS T-Type | eBay I need this version?

I bought a Heppe 178mm X 12mm x 1.0 TL13 and it works perfectly.

Note SRAM UDH mech uses 1.0 pitch axle threads.

How long were shipping times for Canada? My CEF50 has been in transit for over a month. When I search the tracking is just says

“UPS doesn’t have possession of the package yet. Estimated delivery date will be available as soon as we get the package.”

It’s being saying this for the last 30 days.

Normally you have somewhere the name of the ship and with it you can follow their location. For me after crossing to EU the parcel stay several week at landing warehouse before travel to my country

It actually just changed it’s status….

“we have your package, delivery date will be provided as soon as possible”

So for those also getting it shipped to Canada, expect about a month before it gets handed to UPS.

Am I dumb? I removed the motor to make cable routing easier but now can't figure out how everything goes back together. I can see where the 3 cables in the first picture all connect to the motor (one is from the speed sensor, one is from the battery, and one is from the control deck), but I have no idea where the 3 plugs in the second picture go? Any assistance?

the top three are all I used, I know the small red and black female terminals are for a light, the yellow triangle I think is for an optional shift sensor or brake cut off? the small white one, not sure. My cef50 didn't come with that one.

for my build I just shrink wrapped the yellow one, and the red and black pair. and tucked them up under the battery.

Awesome - thanks for the intel Rusty! Much appreciated.

You can clearly see the wiring diagram in this photo. I had problems with that too))))))

Good morning everyone. My engine cover cracked so I made a protector out of Kydex. If it was 2mm thick it would be difficult to mold, or rather the base material (motor cover) would be distorted by the heat, so I made it 1mm thick and it came out beautifully.Kydex is easy to obtain and form...

Hi! Be careful with polarity - I made a mistake and ended up with melting plugs from battery and on motor with sparks

So, my friend managed to make new one:

Also, for v1 frame CC DB Kitsuma - doesn't fit:

But after repair I managed to complete my bike:

I think I will change handlebar - this one (Chinese copy of Gemini Kastor) - isn't round - so display doesn't fit well:

Specs:

CEF50 v1 Large, 720 Wh 48V
Fox 36 E-bike specific
As Kitsuma didn't go well - it is a cheap RS Deluxe Select - will be replaced soon
GX AXS + e13 9-50 cassette
Reverb AXS 170mm
Hope Tech 3 V4 + purple 203mm rotors
Bike Ahead Biturbo E

Use offset bushing to install your shock

Use offset bushing to install your shock

Offset bushings with 8mm bolt will save me 2mm, but I think I need more:

 

[Fresh]

Try it upside down

Try it upside down

Tried - dias touches downtube + it falls forward when compressed - so it is even worse

Ordered offset bushings

Hi all. I suddenly realized that the battery capacity of 700Wh*48V is a quarter less than 720Wh*36V.... However, that said, a 48V motor should be more efficient than a 36V motor. Has anyone done an experiment on how much farther a 720Wh*36V assembly will travel than a 700Wh*48V assembly?

Hello guys, i have an hard time with internal frame rooting (brakes and derailleur) do you guys have any tips ?

Hello guys, i have an hard time with internal frame rooting (brakes and derailleur) do you guys have any tips ?

No tip but I remember it was complicated when you enter the rear triangle
Try to come from the back maybe and then pull ?

Hello guys, i have an hard time with internal frame rooting (brakes and derailleur) do you guys have any tips ?

Start at the back, take the shock off so you can manipulate the rear triangle and create a gap where it goes from chainstay to BB area. Also try getting something smaller through first like a cable and using that to guide the housing.

One tip—

send in a shift cable through, but leave the little barrel out back. Butt the housing to the barrel and heat shrink them together. As you pull the cable it will guide the housing without getting caught up.

I have try many way to eliminate cable , you can think of if I basically try before. Anyway use the AC insulation hose it's the best n easiest method. Now my bike has no cable sound problem.

 

[calvintys]

As for speed sensor , you need to remove you shock and fully compressed your frame to check if you speed sensor it's long enough on the magnet side. Pls check it else u going to have trouble cable being Snape like ne..

 

[souftosouf]

Thanks yall, i just dissasembled the rear triangle and used the cable routing tool (from triangle to bb). Its a very complicated frame.

Just ordered a small v2 frame for my wife..

What’s the real life max dropper insertion depth on a small?

Also whats the stand over height as it’s not on the geo?

Cheers

Anyone have any trouble with their electronics not working? I finally got all my cables routed and reinstalled the motor. Made sure all 3 plugs that go into the motor are nice and snug. Power button on frame will light up but motor and display will not power on. Wondering if I got a dud or if I am doing something wrong?

Unplug all the cable and plug in back again . It's normal where LCD panel does not power up. I usually unplug the LCD section first if can't only remove the motor . Please check your speed sensor has enough room when your shock it's fully compress. I broke my cable before..

 

[souftosouf]

Do you guys had issues with the bolt mouting the battery ? i cant screw them to full length

Same issue with the motor cover

It does seem odd that a company that is said to own the ebike motor market puts so little resources into developing their high end market. Sure they make most of their money off low end motors at very high volume but they can't invest more in our market?

Still we are a DIY group right?
