I love my Switch converted bicycle! Due to supply chain issues, took a year to receive all components and many email to follow up for status. The (AI) customer service eventually reaches humans, but took longer than I expected. I put most of the Kit together, then paid to have the tube, tire and brakes installed properly. The battery lasts less than 20 miles, which leaves me pedaling without ease too soon. Overall, I highly recommend this product to friends and family! I find that my bike is very difficult to pedal as a regular bike, even with the monitor off and battery pack removed. Pedaling is way more arduous and slower. I rode 35 miles and two packs (I purchased a second back-up battery pack) didn’t last 25 miles. Is there a remedy?
