When considering a secondhand bike with a 150cc or above engine capacity and aiming for a comfortable ride with minimal back pain, there are a few factors you can consider:
Ergonomics: Look for bikes with a comfortable riding posture that suits your body type. Bikes with an upright riding position and a relaxed reach to the handlebars are generally better for avoiding back pain.
Suspension: A bike with good suspension can help absorb bumps and road irregularities, reducing the impact on your back. Look for bikes with adjustable suspension or ones known for their comfortable ride.
Seat comfort: Consider a bike with a well-padded and supportive seat. A seat with proper cushioning can help alleviate stress on your back during long rides.
Test ride: If possible, take the bike for a test ride to assess its overall comfort. Pay attention to how the bike feels and if it puts strain on your back during acceleration, braking, and turning.
Brand and model reputation: Research the reputation of the brand and model you are interested in. Look for user reviews and feedback to gauge whether the bike is known for being comfortable and suitable for long rides.
It's important to note that individual preferences and body types vary, so what works for one person may not work for another. Ultimately, it's recommended to try out different bikes and see which one feels the most comfortable for you.
