LaMere eSummit - the ultimate electric fat bike, external battery version

External 630wh Battery Version

We've had a blast riding the best fat e-bikes during the last few winters here in MN, but none of them could fit big 5" tires on the rear or 27.5 fat wheels. Which is so frustrating...So we made our own! Our full-carbon, full-suspension, fat e-bike, the eSummit! It's driven by the latest and greatest Shimano EP8 mid-drive motor. Our eSummit fits the big 27.5 wheel size, with the biggest tires on the market, with frame clearance to spare! We achieve this with a custom offset spider and flared cranks, which make for a perfect chainline and, seriously, the most awesome bike we've ever ridden. The eSummit - the ultimate electric fat bike!


Double Duty!!  Replace the rear end with a carbon Boost rear triangle for the non-snow season and turn it into your amazing XC eMTB summer ride, with 120mm of rear travel on 29ers or 27.5+ wheels. Or, put 27.5 x 4.0" tires on and rip the singletrack in fat mode with the most amazing traction ever, on a bike so light it flies and floats over chatter. The eSummit delivers all the promise of a fat bike without feeling sluggish...the motor sets you free on the trail!


We designed the eSummit with a nice and high BB height (380mm with 4.5 Cake Eater tires and 363mm with 4.0 size), but still with the feel and handling of a nimble XC race bike. You really feel down inside the cockpit with ultimate confidence, yet still able to pedal through any corner or rock garden.

Price: $12,500

Sept. 2023 from Stéphane

Good morning hi...

Just let you know I'm really proud to ride the bike [the eSummit] that you build for's really crazy and faster than Pivot Shuttle XTR.

From Caleb in ID

It's everything I hoped for and is performing consistently great.  Not sure where I end and the bike begins.  It’s super plush but feels tight and responsive.  

It’s a beautiful machine.



From G in AK

Ronny came back from his trail ride from mile 12 to Bear Lake (mile 6) with little spiral fireworks in his eyes. This is a technical, steep trail and he rode the whole thing both ways in boost mode and had two bars left over.

This bike is a winner and can’t be beat in the fat tire e-class.


From Cal in MI
I am thoroughly enjoying my eSummit, it is everything that I hoped it would be! It has allowed me to ride longer and farther than I could before. 

From Tim N in NM

The Bike is a MIND far the most fun I have had on a bike in my 50 years of cycling!

I am blown away by how awesome the eSummit is… it makes going uphill fun!…Railing thru the corners with Fat Tire grip-tion is a blast... Too much enthusiasm to express [in] a brief letter but I assure you I am completely stoked.

From James R. in the Desert

Lots of soft sand, rocks, etc.  The eSummit eats it up and more.  This morning’s 20 miler ride we rode through at least 10 miles of 4-6” sand with no problem. I definitely need to check “nuts and bolts” after two or three rides. My riding partner rides a fatty equipped with the 1500w Bafang set up.  It works well for him.  His bike weighs in around 80 pounds though.  The eSummit handles like a Tesla on the downhills! 


Thanks for the continued support.  You have outstanding customer service!

From Tyler H in AZ

Oh man I have owned a ton of e-Bikes this is the best one ever..... this is the best e-Bike there is.... not only is this the best e-Bike ever, this is the best invention ever!

From Russ A in MI

Just thought I would give a ride report on the eSummit this bike is the best Fat bike ever thanks for the build Russ.

From John B. in Canada

Those are some big miles on what I think is the absolute “BEST” e-assist FatTire bike in the world. I drove 900 miles from Midland, Ontario Canada, to pickup mine a few weeks ago and I couldn’t be more pleased that I did. The bike is everything I hoped it would be and then some. With full suspension, it floats over the bumps and the moguls. For me, the geometry is perfect and the overall performance is magnificent!

I have now logged over 250 miles and can’t say enough good things about the eSummit or the incredible customer service I received while I was in Minneapolis riding and taking delivery of my bike!
