If Ozark is a walmart house brand, they will honor the warranty, I have read that the extended warranty allows battery replacement w/o much drama I think you can get a lot of ebike for $1000 these days, I wouldn't worry that much,

Some mechanical work like adjusting brakes, tuning derailleurs, and greasing parts should be expected as part of bike setup. If you have the skills, then online buying should be lower risk.The last walmart I bought had flat tires and they had to be reseated to hold air. No big deal for me, but it might be a deal breaker for many,

Since you never had a throttle, you;ll never miss it, My thumb reaches in vain for that mssing knob when I ride my regular bike, I want them on all my bikes.
