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).

Flawless Performance and reliability have been flawless for a year. I do worry about the logistics of repair when or if that becomes necessary

There is no better company that builds… There is no better company that builds a better bike, along with support along the way. 9 years riding optibike. Phil Georgiou

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

The Optibike Argon is an awesome e-bike Optibike is focused on quality, customer satisfaction, and amazing customer service. I purchased this bike after many hours of general research and after narrowing it down to the Argon, a few Q&A sessions with Jim Turner himself locked in our decision. My wife is completely satisfied with her new bike as it allows her to ride more with me on longer/faster rides. I feel the reason the Argon works for us is that we had a clear picture of how we expected to use it. Our expectations were to focus on the e-assist capability; the weight and battery capacity were major factors in our decision as well. The standard features Jim included in the build increased the value to us after really comparing what we saw at the same price point elsewhere. We live in South Mississippi, mainly flat with some rolling hills, super hot and humid though. I can say so far the battery has lived up to our expectations. Here's a good example, after a full charge we went on two 32 mile rides, after the last ride, the display showed 4/5 bars on the charge with 62 miles on the odometer. We were averaging 17.5mph and she varied the assist from 1-3 depending on the grade. She loves the fact she is riding faster, her technique is transitioning to spinning more, she loves the fact the Argon is allowing her to ride more and as she said, "who doesn't want to burn more calories". Highly recommend the Argon from Optibike.
