How do belt-drive bikes work? Belt-drive works in the same way as a chain, the belt is driven by the crank and turns the rear wheel. However, belts can’t be shifted between cogs like a chain so they require an internal hub gearing system to change gears.
Are belt drive bicycles any good?
Belt drives are superior to chain drives in many aspects. They are easier to clean and maintain, last longer, and are quieter and smoother as well. However, they are also more expensive, which raises the overall price of the bikes who have them integrated.
Is belt drive better than Chain bicycle?
Belt drives last longer than chain drives- A properly maintained belt drive can last 3-5 times as long as a chain drive. Some riders have gotten 20,000 miles (around 30,000 km) out of a single belt. Most chains only last 3000-5000 miles. Cleaner- Belt drives require no lubrication.
How does a belt drive work?
In belt drives, power is transmitted between at least two pulleys by a belt. One pulley drives the belt (driving pulley) and the other pulley is driven by the belt (driven pulley). In belt drives, the speed is often reduced, so that in these cases the smaller of the two pulleys is the driving pulley.
Which is more effective gear drive or belt drive?
The pinion is the smallest gear and the larger gear is called the gear wheel. Requires less space compared to belt drive. Requires more space compared to gear drive. Low friction loss compared to belt drive, therefore higher transmission and more efficiency.
Does Trek make a belt drive bike?
According to their website, “The belt drive is a carbon fiber composite belt reinforced to prevent stretch. … The worry-free, lube-rejecting, lighter-than-any-chain-you’ve-ever-owned belt also produces a ninja-like quiet ride.”
How long do belt drives last?
With that being said most serpentine/drive belts can last for a very long time before they need to be replaced. The lifespan of the belt will depend mostly on the type of material it’s made of. Older style belts generally last about 50,000 miles, while those made from EPDM can last up to 100,000 miles.
Why would you use a belt drive instead of a chain?
Unlike chain drive, which requires very frequent cleaning, tightening and maintenance, belt drives are relative maintenance free. … Belt drive systems also run much smoother, with much less jerks as compared to chain drives, and produce incomparably less noise too.
Can you change a garage door opener from chain to belt?
Just replace the chain with a belt. The drive sprocket will eventually wear holes in the belt and you’re all set! We have the Liftmaster jackshaft opener linked above.
Why gear drives are more efficient than belt drives?
A gear drive is more efficient than a belt drive. That is because there is no slip between two gears that means power transmitted from driving gear to driven gear has very little to no loss. Whereas there is always certain amount of slip in belt drive which affects its efficiency.
In which drive there is no slip?
Positive drive or synchronous belts rely on the engagement of teeth on the belt with grooves on the pulley. There is no slip with this belt except for ratcheting or tooth jumping.
Can you drive a car with no belt?
Under no circumstances can you drive a vehicle without a serpentine belt because the serpentine belt serves the important function of delivering antifreeze to important parts of the engine. The serpentine belt drives the water pump, and without it, there is insufficient coolant flow to maintain the engine temperature.
How much does it cost to replace a drive belt?
The driving belt replacement cost is usually just between $100 and $200 in most cases, with the belt and part itself costing between $28 and $80, while the labor costs will be between $75 and $120 total.
What are the disadvantages of belt drive?
Disadvantage of belt drive
- Limited Speed range.
- They are not compact.
- Considerable power loss.
- Short service life compared to other mode power transmission.
- The velocity ratio may vary due to belt slip.
- They inflict a heavy load on shafts and bearings.
What are the disadvantages of chain drive?
Disadvantages of chain drives
- They can not be used where slip is the system requirement.
- They require precise alignment compared to belt drives.
- They require frequent lubrication.
- They have less load capacity compared with gear drives.
- Their operation is noisy and can cause vibrations.

Is belt drive a positive drive?
In belt drive, driver and driven shafts are connected by intermediate flexible element (belt). It is a positive drive; so velocity ratio remains constant. It is non-positive drive as slip and creep occur frequently.
