Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
The Nobby Nic tires would work equally well on road, loose dirt, gravel, fire roads, or anything of the like really. The hardtail geometry also isn’t so aggressive that it would be uncomfortable over long distances. Of course, comfort over long distances is key during bike touring. Even though the bike does not come with a rear rack, it does have eyelets for mounting. A rear rack should allow you to carry plenty for a 3-5 day excursion.
Although ebikes are easier to use in some instances, such as climbing hills, there are safety concerns. Because the bikes are heavier than traditional bikes, balance can be a problem. And, of course, ebikes allow people to cycle at higher speeds than usual. “A normal rider will average between 12 to 15 mph, where an ebike rider will average between 15 to 20 mph,” Abadie says. An increase in the number of deaths of elderly male ebike riders in the Netherlands has been attributed to their overconfidence in being able to ride at high speeds and to mount and dismount the bikes.
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
