New V4 Diode 720wh Battery

Main Black Mamba LaMere eSummit V4 720wh

The new Diode V4 has arrived! This new frame takes the bigger 720wh internal battery, which provides seemingly unlimited range, but is also a little bit heavier than our original Diode with the external battery, which is still available. The new V4 frame can be built with the Shimano E8000 or EP8 motor. Bike is ultra-plush with 150mm travel rear, full-carbon frame with a plate that blocks all mud from the rear shock. As pictured above, this bike weighs 48lbs with the big Fox 36 fork and Trunnion mount Float X2 rear with piggyback reservoir, and big 50mm wide 29+ rims, with frost white Onyx hubs and big 3" Cake Eater tires. This is the most awesome eMTB we have ridden!

Customer Review from Jim K on 11.16.2020
The frame is crazy stiff.  I mean REALLY stiff.  Love it.  Big guy friendly. First DI2 bike.  Hated it in first 5 minutes, then loved it by end of the ride. The fox 38 is super plush, stiff and fun. I ride dirt bikes as well.  Its a very dirt bike like fork.   I would urge all buyers to to go this way.  It matches the stiffens of the frame nicely. I noticed the thing is Bluetooth enabled.  Didn’t realize that.  Super cool.  Love adjusting the power ratings per mode. The frame is on the big size for large.  Kept the seat post slammed as low as possible and was just barely low snuff at full extension. 29+ is the right set up in my mind.  Glad I did that. The bike pedals surprising well.  Did alot of zero boost pedaling on flat trails riding with wife.  I would way it pedals better then a turbo Levo with no boost on. The amount of power in “boost” mode is very Moto.  Can’t really imaging needing more power off-road.  I was a little worried about the power output of the e8000 vs the Levo.  But its a non issue. Overall, this is an AWESOME set up and I love it.  Really appreciate the professional details on the build.

My La Mere E-Bike     Game changer!

I just got my LaMere E-bike on Sunday December 27th and it is a game changer.  On Friday December 25th I went riding on my regular mountain bike in the cold and wind.  I dreaded it and rode my most comfortable trail for a total of 7 miles.  On Sunday, I got on my E-bike and was excited to go ride in the cold, wind and snow.  I rode trails I normally would not pick and explored finding snow and ice.  With an E-bike, you don’t mind challenges.  I rode 23 miles exploring trails I would not try unless I was riding with my husband. The LaMere E-bike is amazing.  You still get a great work out and I ride even harder because the more you pedal, the more assist you get. It is giving me confidence to ride more technical parts of the trail and ride it with speed.  I look forward to riding my LaMere E-bike every day that I can!

Original 42lb Diode eMTB External Battery


The LaMere Diode with Shimano E8000 Motor

Hand-Built in Minnesota Any Way You Like 

We designed the LaMere Diode to fit 29+ wheels as well as 650b+, so if you like fast XC riding and maintaining speed thru corners and rock gardens, then this is your eMTB. When we build it with 100% engagement Onyx hubs and the nearly 100% engagement Shimano E8000 motor there is no play in the cranks, which makes you faster and makes your drivetrain last way longer. This frame is 1.5lbs lighter than our new V4 Diode so can build the whole bike up lighter for whipping thru singletrack. We have internal battery versions, but our favorite is the lighter, less maintenance new 630wh Shimano external battery version. With the perfect 370mm BB height, the Diode is the ultimate XC and AllMtn eBike. And, of course we can build it up any way you like with any suspension from Fox, RockShox, DVO, MRP, etc... with any groupset, any cockpit, any options you want. All Diodes are hand-built by our super mechanics here in Minnesota and shipped to you directly, saving you about $5000 and about 4lbs in weight compared to mainstream bike industry bikes. 

Just a little uphill air on the Diode...

Check out the Diode in semi-Fat Bike Mode!

Simply mounting a 4" Terrene Cake Eater studded 27.5 tire on the rear on a 50mm wide rim allows it to work surprisingly well on the snow, especially groomed singletrack or snowmobile trails. If you want the best actual eFat check out the eSummit which fits EVERY wheel/tire size.

The XT Di2 shifting runs off the main battery, and the new Firebolt Switch Unit incorporates the same design and shifting feel as XT Di2 and makes flipping through power assist modes as easy as shifting gears. Read more on the Shimano E8000 system HERE.

Like all LaMere bikes we will customize your build any way you like and sell it to you directly at an unbeatable price!

Shimano Drive System

The amazing new Shimano E8000 motor and drive system features nearly 100% engagement with a completely user-tunable interface. Carry an extra 5.5lb battery for longer rides and quickly swap it out with the turn of a key. Deore XT cranks with normal Q-factor and Shimano Hollowtech II bottom bracket for added strength and direct power transfer. Unlike other E-Bikes that suffer from huge lash or play in the cranks, the Shimano motor in combination with the world's best instant engagement Onyx hubs creates a fully engaged riding experience unlike any other E-Bike.


Like all LaMere bikes the Diode can be built up just the way you want with any grouppo, wheelset, suspension, tire combo, and cockpit you want. We can also sell you just the Diode frame with complete Shimano motor, battery, cranks, display and electrical system, and Fox Float DPS Trunnion Mount Factory shock.

Take it one step further and add an XT Di2 rear derailleur, rear shifter, cassette and chain. The Di2 runs off the main battery so there is no need to ever recharge, and it uses the same display unit as the main system, making this a versatile and easy to use system.
