Which is better for a heavier rider?

The 750W bike. It is rated to 365 lbs against 264 lbs for the Adistar OS01. If you are near or above 264 lbs, the Adistar is outside its stated limit.

Is the Adistar worth it at $255.99?

Yes, if you fit its 264 lb limit and 4'11" to 5'11" height range. You get full suspension, dual disc brakes, a removable 48V 15.6Ah battery and a peak 1500W motor for about half the price of the other bike.

Which has the longer range?

Both claim up to 65 miles in pedal assist. Real range depends on rider weight, terrain and assist level, so treat both figures as best-case.

Do either have gears for climbing?

The 750W bike lists 7 speeds, though its own description says 6-speed. The Adistar OS01 lists no gearing, so climbing depends on the motor.

Which is safer to charge at home?

Neither listing shows an NRTL safety certification, and the 750W bike explicitly says it has none. Charge either one on a hard surface, unattended-free, and follow the manual.

Is the 750W bike worth the extra $243?

Only if you need the 365 lb load rating or the gearing. On motor power, battery removability and price, the Adistar OS01 comes out ahead.
