E-bikes ask a lot of cranks. The motor is constantly feeding in torque that would buckle a lesser arm, and the added weight of the system means rock strikes and pedal strikes happen harder and more often. The e*thirteen e*spec Plus is built specifically for that reality, using forged aluminum construction that keeps up with motor-assisted power delivery without creaking, flexing, or letting you down mid-climb.
One of the sneaky upgrades here is the slimmed-down Q factor and low-profile arm shape compared to older e-MTB crank designs. That narrower stance lets riders lean deeper into corners and pedal through tighter sections without clipping a pedal on a root or a rock. Fewer pedal strikes means more momentum kept, and more momentum kept means faster, more confident riding from the bottom of the trail to the top.
Compatibility is another win. The e*spec Plus works across the most popular e-MTB motor platforms, including Shimano EP8, Bosch CX Gen4, and Brose S Mag systems, so it fits the bike you already have. Pair it with e*thirteen's direct mount chainrings for a clean, rattle-free drivetrain setup that looks as tidy as it performs.
Tired of clunky, wide-stance cranks that clip every rock on a tight switchback? The e*spec Plus fixes that with a genuinely slim profile that gives your ankles and your confidence more room to work with. If you push your e-MTB hard on technical terrain and want a crankset that keeps pace with your motor without adding drama, this one was designed with you in mind.
