    Ecotric 20" Folding Fatbike

    Hi travlinjones, I just got my tape measure and see the following: The theoretical lowest seat positioning would be about 31 inches (assuming a ~4 inch thick seat from bottom to top). The top of the tube the post goes in is about 27 inches off the ground. The potential problem for you is the...

    Ebikeling 1200w rear wheel kit from Amazon

    Nice! Is that battery bag and rack (between your knees) a custom job you rigged together yourself or something you can buy? Also, do you have enough room to pedal without your knees rubbing it? I would imagine it would nice to get the weight of the battery centered a bit too (versus out in...

    Ebikeling 1200w rear wheel kit from Amazon

    Here’s what became of the 700c Kit on the mongoose bike. I moved (along with the air fork) to 700c Trek Verve Disk 1. Man, the Trek Verve rides nice.

    Ecotric 20" Folding Fatbike

    Alright, I moved my 700c kit (and air fork) from the Mongoose mountain bike to a Trek (Verve Disk One). Wow, duh, but the Trek Bike rides 100X smoother... I’m done for a while.

    Ebikeling 1200w rear wheel kit from Amazon

    Here’s the Mongoose Impasse Build. I think I’m going to move this kit/battery/build (and the air fork) to a 700c Trek Verve Disk 1. The rear suspension forced me to an (innovative) Hule rack that works fine, but feels a little rickety.

    Ebikeling 1200w rear wheel kit from Amazon

    Yeah, my stingy gene and self preservation instincts had a debate about that. The $77 (10 Ah) batteries are not the every day batteries. They’re only for when I need to get more than ~30-50 miles (assuming the $277 48v/20AH gets me that far), which is probably about never. I have irrational...

    Ebikeling 1200w rear wheel kit from Amazon

    I know what you mean. It’s not bad for me yet, but it’s a hurdle.

    Ecotric 20" Folding Fatbike

    Here’s the Mongoose (impasse) bike build. The battery was a 15 inch long monster and all rear rack bags seem to top out at 14 inches... So, I bought a motor cycle bag and rigged it all up to fit. Also, the rear suspension left few options for the rear rack, so this (less sturdy but effective)...

    Ebikeling 1200w rear wheel kit from Amazon

    Here’s a bike I just built with the 26” fat tire Ebikeling (1200 W) kit. I converted a Saigula Fat Tire with: 1) 1200 Watt Ebikling kit ($375) on Amazon. 2) 48v (50 AMP continuous discharge) 20 Ah battery ($277) from AliExpress. (Only 10 days from China to Chicago). So far so good on quality...

    Ecotric 20" Folding Fatbike

    Hi Larry, I’ve come a long way as a bike mechanic since I successfully changed that Ecotric (rear flat) tire. I just finished building this 26” fat tire Saigula bike ($450 on Amazon) into a beautiful ride electric bike ($375 48v 1200w Ebikling kit on Amazon) beast. Got it up to 30 MPH and...

    Ecotric 20" Folding Fatbike

    I’ll end up using one (probably air fork) on my Sondors Fold X if it fits.

    Ecotric 20" Folding Fatbike

    I might do the same. Let me know how you do this when you’re done. I ordered an Ecotric for my big brother for his birthday. He rode mine on a vacation last week, and he loved it. He lives in Austin, so he has nice bike riding weather year-round. (He’s 5’7” versus my 6’3” and it fit him...

    Ecotric 20" Folding Fatbike

    FYI - Air fork on ebay for $229 + $29 shipping. I think it’s compatible, but I’m in no rush to try this again anytime soon. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F113782936832

    Ecotric 20" Folding Fatbike

    I realized I didn’t install the fork correctly the first time. The (screw cap thingy) in the fork was lose (as I tried to re-use the one from the Ecotric) creating a loose steering wheel feel. I finally figured out what it was called (headset Star Nut for fork - pic below) and ordered more of...

    Ecotric 20" Folding Fatbike

    This same thing happened to me when I got caught in the rain on the way back from a vacation with the bikes on a car rack. I had taken out the batteries and wrapped plastic bags around the display panels, but there was really no good way to cover the Ecotric controller box, which looks water...

    Ecotric 20" Folding Fatbike

    I got the ($105 on EBay) suspension fork installed per your suggestion. Not too bad. I’ll figure out how the hell to set it tomorrow. It’s a different ride with the front ~3 inches higher. Not better or worse per say. Just different.

    Ecotric 20" Folding Fatbike

    This is a very good point. I actually bought a second battery for the X-Treme E-Rider Mini because of the highly specific battery dimensional needs. I’ve gone though enough battery powered devices over the years to know how much it would stink to have an otherwise perfectly functioning EBike...
