Pros: Good speed, good range, good power (lithium), nice size
Cons: Lead-acid battery version could use more power for hilly country.
I own two RMartin Limited EVD scooters, a lead-acid battery powered EVD scooter and a 40 AH lithium battery powered EVD scooter. The range is good for both scooters, although to go 50 miles on a charge one has to be very conservative with speed and acceleration. When driving at a speed of 40 MPH to 45 MPH, I normally can expect a range of approximately 30 miles.
The top speed is approximately 50 MPH on level ground with a 250 pound rider. Both scooters have good acceleration, but the scooter with lithium batteries has better acceleration than the scooter with lead-acid batteries. I live in an area that is quite hilly, with some hills having a rather steep grade. The lead-acid battery powered EVD scooter seems limited in power to pull hills. However, the 40 AH lithium battery powered EVD scooter pulls hills quite well. Therefore, I will assume that the new 60 AH lithium battery powered EVD scooter should pull most hills very well while holding a reasonable speed.
Both scooters hold the road well, track well, and brake well. The fuel efficiency is great. I am in the process of purchasing a 60 AH lithium battery powered EVD scooter for extended range and even better hill climbing ability.
