Here are some clips of a few hill-climbs at Carnegie SVRA/OHV park near Tracy, CA, on Alta Redshift electric dirt bikes.
This is my son Dylan doing various hill-climbs from mid to late 2022.
The motorcycles are:
2017 Alta Redshift MX (yellow bike)
2018 Alta Redshift MXR (white bike)
The Alta electric dirt bikes are excellent for hill climbing, as they have a ton of power (50 hp & 142 ft. lbs. of torque) and you cannot stall them on the hill. You can also hear the tires as they start to lose traction, so you can adjust throttle inputs. The electric motor provides all of its torque at just about anywhere in the rpm range, so you don’t have to worry about keeping the revs in a specific power-band or feathering the clutch.
Maintenance is simple, so you don't have to worry about oil changes, air filters, or many other tasks that would be common on internal combustion bikes. Plus, they are just super fun to ride!
