Alta Motors Recalls Redshift EXR and MXR

Certain units require a software update

Electric bikes are like big computers that you ride on instead of using to watch cat videos. Despite all the new technologies, not even e-bikes are immune to recalls. Alta Motors that recently christened its new EXR electric dirt bike now has to bring all its Redshift models into the shop to fix a software issue. Do you think there's an Alta Genius Bar?

Some 2018-2019 units of the Redshift MXR and new EXR are targeted by this recall. It's been discovered that while riding on either of the Redshifts, if the throttle is twisted forward past its natural "closed" position (so cutting the throttle manually rather than letting the handle spring back into place), it could cause the vehicle to stall. Apparently, you can stall an electric bike. At highway speeds, a stalling bike could be a safety hazard.

“With the current firmware, rolling the throttle forward while in drive mode will shut down the motorcycle, displaying ‘Inverter Throttle Fault," reads the hq notice sent to the dealers.

MXR 2019: 56PARAEM_KB000367 – 56PARAEM_KB000488
