Motorcycle Consumer News has published a four-page review of the C-Evolution in their January 2018 issue. A few things in the article caught my eye:
The motor is said to produce 48 hp and 53 lb.-ft. of torque, "from 0 rpm to 4500 rpm", however the power curve chart included with the article shows the power being produced is 44 kW at 7,500 rpm and torque as 63 Nm at 6,000 rpm. I get the feeling that may be the chart for BMW's C650GT IC scooter.
The article states that its regen can increase the scooter's range by 10 to 20%. Frankly, I find that statement hard to believe. In my personal experience, after owing 5 electric motorcycles, it is more like 1 to 3%.
Acceleration to 30 is said to take 3 seconds and to 60 mph, 7 seconds. No quarter-mile performance was provided. Top speed is electronically limited to 80 mph.
The bike is powered by 36 Samsung SDI li-ion cells (133V nominal), with a total capacity of 12.5 kWh (nominal?). Advertised range is 99 mph in Eco Pro mode. The reviewer said that they were able to obtain 9.8 miles per kWh while riding "assertively" in the city and 11 miles per kWh while "babying" it in city riding. "In a worst-case test, with the throttle pinned for 46 miles, it still returned an astonishing 4.9 miles per kWh, and that was in cool weather." (That calculates to 61 miles for the 12.5 kWh battery capacity.) The scooter will travel about 3.7 miles after its display shows that the pack is depleted.
In addition to ABS, the scooter has traction control to prevent rear wheel spinning under slippery conditions.
The scooter has an on-board level 2 charger that connects to a J1772 charging receptacle and also a separate 120VAC charger, so that the bike can be charged from a home wall outlet. Charging times are 9 hours, 20 minutes at 120V, or 4 hours, 30 minutes using the 3kW, 240V system.
The C-Evolution's 12 volt systems are powered by a separate 12V, 8Ah battery, rather than a DC-DC converter.
Suspension travel is 4.7 inches front and 4.5 inches in the rear.
What really got my attention is the weight of the scooter. 606 pounds, fully charged.
That is 31 pounds more than BMW's IC scooters.
Seat height is 30.1 inches with the standard seat and 30.9 inches if you are sitting on the "comfort" seat.
There is a storage area under the passenger seat that can hold one full face helmet - once you remove the 12V charger stored there.
An accessory "touring" windshield is available - no doubt at a substantial extra cost, based upon my BMW buying experience.
The color TFT instrument display is 7.25 inches wide by 3 inches high. (Isn't it about time that Zero changed their display to a color TFT, also?)
An interesting chart was included in the article comparing the cost of riding a C-Evolution and a BMW C650GT for 12,000 miles, based upon $130 per hour labor cost (which is what I pay at my BMW dealer). Here is the breakdown:
C-Evolution: 7.7 MPkWh, at $0.09 per kWh (about half of what I pay) = $140.26. Maintenance costs = $455, for a total of $490.26.
C650GT: 51.3 MPG at $2.85 (I pay 50 cents more per gallon) = $666.66. Maintenance costs = $1,716.00 (ouch!), for a total of $1,986.66.
