I am 61 years old and there is nothing that can touch the Optibike R11. I like the range with the extended touring battery combined with the power and speed. I have completed several 100 mile trips and plan in the Spring of 2014 take a 400 mile trip from Pittsburgh to Cumberland Maryland.
When you turn off the electric mountain bike it feels and rides like one of the best mountain bikes. It’s a bike! Even though the Optibike weighs 60 pounds the high quality components offset the weight. I love the speed of the R11 even at 60 pounds and 73 pounds with the external touring battery. I cover more distance in less time with the Optibike and it helps me stay strong on my bike at 61 feeling like I am 20 again. What an awesome time I have on the R11.
