It was simply final November that we heard in regards to the DirtySixer AllRoad Mark II, a jumbo 36-inch-wheeled bicycle for large riders. Well, these large cyclists will quickly have an electric-assist possibility, within the type of what’s at present being known as the eDirtySixer.
Presently in prototype type, the brand new mannequin was designed by DirtySixer founder David Folch, who himself stands 6’6″ tall (198 cm). Like his previous creations, it features a 6061 aluminum alloy frame which is proportional in size to its 36-inch wheels, so (for vertically gifted cyclists) it handles like a regular bike. In its present incarnation, the rider’s pedalling power is augmented by a 250-watt Shimano STEPS e8000 bottom bracket motor, which is itself powered by a down-tube-integrated 500-Wh lithium battery pack.
This setup takes the rider to a top pedal-assisted speed of 20 mph (32 km/h), with one charge of the battery reportedly being good for a range of approximately 60 miles (97 km).
That said, Folch told us that an upcoming prototype will utilize a Bosch mid-drive unit, followed by one equipped with the Valeo Smart e-Bike System. The latter is a bottom bracket-located setup which features one of Valeo’s 48-volt electric motors, along with a 7-speed adaptive gearbox made by partnering company Effigear.

The complete factor suggestions the scales at round 65 lb (29 kg) with the MRP, or a number of kilos much less if consumers go the inflexible route.
Whatever its official identify finally ends up being, and no matter motor it makes use of, we have been advised that the eDirtySixer will likely be accessible for preorder inside a number of weeks, for supply in mid-2023. The suspension and inflexible fashions must be priced a bit above and under US$8,000, respectively.
