Juliet III
When I purchased the Juliet three, I found that the gearing between the front and rear sprockets made it such that at any speed over 15 mph. You could not keep up with the peddling. Jara was very responsive and sold me a larger sprocket so that now at least up to 20 miles an hour I am able to petal assist When riding. Long-term I think they need to re-look at the design because I’m sure there are people who would like to be peddling at the maximum speed of 30 miles an hour, which currently is impossible.
