When I was building up my CYC X1 Pro Fatbike, I ran into a lot of conflicting information on gearing choices for the motor. I’ve ran the motor for a few seasons (600kms) now and have tried three different gearing combinations, so I’d like to share my experiences to try to help others make their...

Sounds like a great solution! Attach some pics when it’s completed!

A large battery can really put alot of stress on the bottle mount screws. On my other fatbike, which has an aluminum frame, I put a massive 14S6P battery mounted directly to the frame and after a couple of light crashes/tipovers, I had almost ripped both rivets right out of the frame. I...

Grin Technologies out of Canada makes a product called a triple bob that reinforces the water bottle mount area. Definitely highly recommended for a carbon frame: Haystacks, have you tried bottoming out the rear suspension to check the clearance with the 185x50? Melody from Dengfu advised me...

Grin Technologies out of Canada makes a product called a triple bob that reinforces the water bottle mount area with a plate attached to the water bottle screws and then secured by hose clamps. I used shrink wrap around the hose clamps to prevent the frame from damage. Definitely highly...

Nevermind, found it. https://wafabike.com/product/extra-battery-emtb/

Thanks Daxxie!! Can you send me a link to the last battery? Couldnt seem to find it online. Thanks!

Hi Daxxie, I’ve got a Dengfu E06 on order, and I’ve been following along with all the builds of the frame I can find (yours, Jon A, Haystacks). I’ve got most of the parts ordered, but I am struggling a bit with the battery. My original e-fatbike build has a 1092Wh battery in an off the shelf...

I had to source mine from Europe. They are very hard to find in North America. I think they are made for OEM e-bikes and most shops don't carry them.

I'd second the DT swiss 350 hub with the star ratchet system, steel cassettes with pinned gears and the steel freebody hub. That is the most durable system I've come across. One other thing to mention is upgrading to a rear derailleur with a clutch that can increase chain tension. Increasing...

It's in Northern Alberta (Canada).

Went for a winter ride in the river valley with my dad’s Specialized e-bike. It had 27.5 Plus sized studded tires. The power of the bike allowed you to explore the creek and river valley area. After that I was hooked and decided to build my own custom fat-e bike. At the time, COVID had hit...

Haystacks, what rear shock do you have on the bike? I've been looking for a coil shock for this bike and can't find one that fits in the frame.

Eunorau Specter S is a dual battery option. You can run it as a fatbike or plus tire bike

CYC X1 stealth would be a good option for a mid drive setup. Not as cheap, but you’d get much better torque for climbing and off roading if that’s your thing. And fatbikes usually have tons of room in the main frame triangle for large batteries.

One other thing to mention is the available wattage for the front/rear lights coming directly from the motor wiring is extremely low. It won’t power most commonly available lights that have any amount of lumens. I’ve heard you can run into issues if you exceed the available wattage and could...

Just my opinion, but if it were me, I’d sell the bike (I have this bike in Carbon non-motorized- it’s a great bike!) and buy the the factory built Giant Trance X e-bike. Mounting a heavy battery on the top tube will ruin the dynamics of the bike, and won’t let you get on or off it very easily...

The Shimano 12 speed Deore cassette is all steel ,mostly pinned cassette (up to the smallest 4-5 cogs I believe). It is the best option for an ebike on the 12 speed Shimano system. That’s what I’m running on the Dengfu fatbike I’m building up this fall. 10-51 gearing, all steel construction...

Thanks for the post and all the information Jon. I have a Dengfu E06 frame on order and will be building it up over the fall to be ready for some winter riding!
