I’m 6’4” and my legs are longer than normal for my height; I have almost a 36 inch inseam. So I purchased a longer seat post. I bought a SENQI Bicycle Mountain Bike seat Post Aluminum, 28.6 mm diameter, 450 mm length. That allows even more height than I need, and works great! Senqi sells a lot of different diameters to fit any bike.

The Ride1Up 700 Series looks good at $1,500 and is more powerful than the $750 Nakto Classic. Nakto is perhaps the least expensive eBike you’ll find. Both use a geared rear hub motor. Those are better than ungeared ones on hills but not as good as mid-drives. The Ride1Up is more powerful.
