I bought a Turbo Tero one year ago here in Hawaii. I am very happy with its performance this past year. Here in Hawaii most roads are narrow and congested with confused tourists from all over the world. Many hills are shortcuts for me and this ride can handle a pretty steep climb in the lowest gear, although it has its own limits. When I get so steep I need to jump off, it continues up the grade on its own power, without any pushing from me. I use the battery wisely as suggested in the app. I never go below 20% or higher than 80%. At last battery health check, the self diagnostics put my battery at the highest level of health, and I ride everyday except when raining. I chose the Turbo Tero because the balance between performance and price, while getting the advanced over engeneering that Specialized is known for was a no brainer in our crowded e-bike world. The brakes are outstanding on steep downhills. I had the front cargo plate installed which helps with many trips and looks cool. I record each ride on the Specialized App which gives me a good look back at my health progress from each ride. Sometimes the app has snags and rips me off half of my ride, and a few times dropped the entire ride completely. I’ve had to delete and reinstall the app and re program the computer on the bike which was simple and straight forward which fixed things. I will be selling this bike soon while it’s relevant and purchasing a new one. I hope to get 70% of my purchase price, but who knows? Conclusion: The Turbo Tero is only one of a few twenty-niners on the market with this level of value, economy, quality, and hopefully soon: RESALE VALUE. 4 Stars
