We have had a blast riding the best fat E-Bikes during the last few winters here in MN, but none of them can fit big 5" tires on the rear nor 27.5 size fat wheels, which is so frustrating... So we made our own! Our full-carbon full-suspension Shimano E8000 mid-drive motor eFat Bike, fitting 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 perfect a chainline and, seriously, the most awesome bike we've ever ridden.

 

Replace the rear end with a carbon Boost rear triangle for the non-snow season and turn it into your amazing summer ride. Or, just put 27.5x4.0 tires on and rip the singletrack in fat mode with the most amazing traction ever, on a bike so light it flys and floats over chatter. It delivers all the promise of a fat bike without feeling sluggish... the motor sets you free on the trail!

 

We designed the bike with a nice 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 but able to pedal thru any corner or rock garden.

Price: $12,500

From James R. in the Desert 12.2020

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!
