What riders ask about the OT08 PRO
How much does it weigh?
The OT08 PRO weighs 39.2 kg. That is 15% above the median weight of 34.2 kg for its type. This is a heavy e-bike. You will feel the weight when lifting it or pushing it uphill.
How much torque does it have?
The motor delivers 65 Nm of torque. That is 19% below the median torque of 80 Nm for its type. With a hub motor, this torque is moderate. It should handle gentle climbs, but steep hills may require more effort from you.
What speed class is it?
It is a standard pedelec class. The motor assists up to 25 km/h. There is no throttle. You must pedal to get assistance.
How far does it really go?
The manufacturer claims a range of 190 km. MathBikes estimates the range at 98 km, with a band from 86 to 109 km. That estimate is 48% below the claim. The estimate comes from a formula, not from testing. You can adjust the inputs with the range calculator.
What does it cost to run?
The purchase price is 1727 USD. Running costs depend on electricity and maintenance. The battery is large, so charging it will cost more than a smaller battery. Use the cost calculator to estimate your own costs. The warranty is not listed, so factor that into your decision.
Where it falls short
The OT08 PRO makes a clear trade-off. Its massive battery adds weight and cost. You get an estimated range that is double the median, but you also get a bike that is 15% heavier than average. The motor torque is below average, which may limit its off-road capability.
Who should buy it
This bike is for riders who want maximum range and do not mind the extra weight. It is not for riders who need to carry the bike often or who ride steep, technical terrain.
- Long-distance commuters who want to go many days without charging.
- Riders who prioritize battery capacity over motor power.
- People who ride on flat or gently rolling terrain and value a stable, heavy feel.
Look elsewhere if you need a light bike for lifting onto a rack. Also consider other options if you want strong hill-climbing torque. The OT08 PRO is a niche product for a specific kind of rider.
