Hi and welcome to the forum!
I’m 62yo. I do have back/neck issues and minor knee issues. I’m really active. I’m in a similar boat as you. I have two very nice bikes in my garage collecting dust. A touring bike and full suspension mountain bike. Big money in both. But they are difficult for me to ride comfortably any longer. I might try the mountain bike again. We will see.
So far I’ve purchased 8 e-bikes and built one custom mid-drive e-bike.
I do not live in an area that is mountainous or has tall long hills. If you are going to do serious off-roading or hill climbing opt for a mid-drive. But otherwise hub motors are fine.
I have finally settled on a 1000watt 9-speed fat tire bike with front air fork. It uses combined cadence and torque sensors for pedal input. It’s made by JUICED and they are clearancing their silver full frame version and yellow step through version. $1499 & $1399 respectively. It’s called a “RipCurrent S”. They also sell an upgraded controller that is 2000watt and allows throttle control past the normally limited 20mph.
This is a killer deal for a 1000watt bike with torque sensor. I’m think they are on sale until they are gone. I purchased both of those bikes for my wife and I. The only negative is that the hydraulic brakes they come with aren’t great. A pad swap and 203mm rotor for the front helps quite a bit. But I opted to install Magura MTE5 4-piston brakes. The code to get the $100 off is VIP100 or if you were military, first responder, medical, teacher or student they have a link to get a $100 off code from VerifyPass.
There are several videos on YouTube for this bike. But they recently upgraded to the 1000watt hub so not much on YouTube about that. Also these bikes come with a whopping 52v 19.2ah battery. Here are the links if you are interested.
The go-anywhere, do-everything, most versatile fat-tire e-bike, the new RipCurrent S, is packed with tons of premium components. Check them out here!
