Hi There! I'm new to this forum and also new to the world of e-bikes. Have been test riding a ton lately to determine one that I can use to begin to commute to work in a hilly city. I test rode several Terns last weekend and liked the S10. There is a used 2017 for sale locally for $1,900 and has 650 miles. Considering that a new battery would cost $900, I'm wondering if this is a good price or not. The total cost could end up at $2,800 and given that the new Quick Haul P9 will start at $3299 with a warranty wondering if this is the better deal? (I realize they are different bikes). What would be a fair price for a 2017 Vektron S10 with 650 miles? It's hard to find any comparisons online. After reading lots of the posts here, it sounds like the 2017 has the Active Line motor and wondering if that would be enough power for the hills? (Can't test drive one at the bike shop to know how it would compare to the 2022 S10 that we rode). Any thoughts or advice? thanks in advance.
