im amazed at the power and efficiency of a 20 inch DD wheel. I hopped on my trike to go upto the store and the ca3 said I consumed 3ah for 34km travelled. im used to a ca2.3. so I was just kind of staring at it thinking no way maybe that's top speed but no. ive been upto 50kmh on it. so I get home and use grins motor simulator. in a 20 inch wheel, 52v 11ah battery,40 amp controller, 60% throttle. I can go 32km/h for 105km without pedaling. in a 26 wheel same set up, but 50% throttle, speed is 33km/h range 108km.
I don't know if efficiency is the right word because it takes the same amount of energy to move from A to B. I just had this notion that this little wheel would be slower top speed with less range but whats happened is I have a slower top speed but alot more usable power/torque at my usual riding speeds of 30 to 50km/h and off the line at lights with pretty much the same range.
I even think you can mount moped tires directly on the 20 inch bike rims
first kit I ever had was a 48v 10ah 500/1000 watt geared bafang, 20amp controller. topspeed 32km/h and range was maybe 25km. I liked it but it sucked.
