I'm Ed from Souther New Hampshire. Just ordered a a Juggernaut Classic HD from Roshan at Biktrix. Looking forward to day of arrival. Reading many of the posts have been very helpful in my research to select which Ebike to buy? I recently had two knees replaced and found the discussion regarding a note from my doctor stating riding an ebike is medically recommended or necessary. I have an appointment with my doctor and it would be useful if anyone was aware of any supporting articles of the medical benefits or necessity of riding an ebike for knee replacement rehab. if anyone would like to go for a ride around south NH or Northern MA please email me.
