These bikes still appear to be quiet… These bikes still appear to be quiet the bike with all the low power slow moving Chinese bikes; opti bikes are like a breadth of fresh air. The ride feels un inhibited like you are free in the wind. A couple on road bikes decided to pass me on a narrow dirt trail in which the speed I was doing felt comfortable; they seemed to pass me like I was another slow ebike. The trail went back to concrete and was quiet wider I passed them in just a few seconds and they scoffed at me and stopped. It was very odd but I kept going with a smile on my face and my pedals still like they were frozen in place.

I bought an Allroad a few years ago and… I bought an Allroad a few years ago and have really enjoyed the bike. Great workout when I want it, and easy riding when I don’t. I spent a lot of decades pushing things to the limit, but now I can control things! Great service from these guys as well. Very happy!

Top-of-line, high-powered e-bike; with room for even greater innovation Pro's: Powerful and fast, sturdy and well-built (in USA) with high quality parts; good range and great hill-climbing ability; friendly, excellent and responsive service and back-up (Thanks, Jim!); 8 years and still running strong! Con's: can be unstable due to slightly high center of gravity (R15, especially if using range-extending 2nd battery off seat stem tube); gearing seems too low on my model, for my use and comfort, which makes it difficult to pedal (and work-out) when using power assist at faster speeds (a higher/wider gear range would add more versatility).

pro forms as advertised pro forms as advertised the roloff 14 speed hub does take a few miles to'wear in' have got as many as 50 miles out of a charge the fenders are kinda cheesy rear fender was easily broken the front was removed because of clearance difficulties... any mud or gravel would grind between the tire and the fender... changes i would make... gates belt drive the worst problem is parking... bike thieves deserve a slow death !!!

Optibike - High Performance eBikes Optibike - High Performance eBikes I bought my first Optibike (OB-1) in 2007 when I recognized that hub-motor eBikes do not work well on hilly terrain. Today I use one elite Optibike for commuting (22 miles RT) and another for off-road use (R15c). Both the machines and support team have been very solid and responsive. In summary, I have incredible respect and admiration for this entrepreneurial company. Christopher Pederson Las Vegas, NV
