As a long distance cyclist who turns 81 next week, I have been using an EBO Burly (Electric Bike Outfitters) electric kit on a cross-country or border to border ride each summer since 2017, covering over 28,000 miles of the 40,000 miles pedaled on my twelve tours. I have just completed my last long ride beginning in Olympia, Washington and finishing up on the GAP/C&O Canal Trails coming into Washington DC. No BS, I have seriously abused their product many many times, especially in the Sierra/Cascade, Rocky and Appalachian mountain ranges, but the motor was durable and outlasted me. I highly recommend the EBO as a quality product on any kind of bike that you might have. Other uses: Outrunning dogs, headwinds, keeping up with unloaded tag-along riders, from stopped to getting up to speed on a slope and quick-shooting those short steep hills. Jack Day
