Hi folks. This is just a quick preview of the upcoming electric freeride dirt bike project. The design is kind of a mash up between a Sur Ron and an LMX freeride bike. I tried to incorporate the features that I liked best about both bikes into this one.
The motor will be the QS 165 that's rated for 5kw continuous and 8kwp, 5300 rpm and 33ft-lb of torque at the shaft. It'll be coupled with the ND72530 Far Driver controller and powered by a removable 65V, 36Ah li-ion battery. It'll have a 7:1 sprocket ratio driving an 18" rear wheel which should produce a top speed of around 85 km/h and over 230ft-lbs of max torque.
The wheelbase will be 51" and the rake angle will be 27°. It'll have DNM M-200S forks in the front and an RCP-2S rear shock controlled by a progressive dampening linkage to provide 8" of travel for both wheels. The total curb weight should be somewhere between 120-130lbs.
I had to put the street bike build on hold after discovering an unexpected overrated capacity issue with the cells that I originally chose for the battery when I began testing and prepping to build it. I won't get back to work on it until I get replacement cells ordered and delivered, so in the meantime I'll be getting a head start on building this dirt bike. Let me know what you think in the comments!
