Which type of chain case?

If you have a preference for the type of chain case on your e-bike, it is a good idea to include it in the selection at an early stage. This is because the choice of a type of chain case will affect the position of the motor and/or the type of gears. You have a choice of three options.

Enclosed chain case

An enclosed chain case is the best option for the useful life of the chain. The chain case protects the chain against moisture and dirt. What is more, the chain case also protects your clothes: the enclosed configuration means that you won't get any lube on your clothing.

Advantages

  • The chain case protects the chain and your clothing 
  • The chain needs no maintenance

Disadvantage

  • The chain case cannot be combined with a derailleur

Can be combined with

  • Motor position: front-wheel motor and mid-mounted motor 
  • Gears: hub gears or automatic gears

Semi-open chain case

Like an open chain case, a semi-open chain case is very light, but provides the chain with little or no protection. The chain is exposed to dirt and moisture which means it will require maintenance. Using a chain guard protects your clothing against chain lube and splashes of dirt.

Advantage

  • The chain guard goes with a derailleur 
  • It is light in weight

Disadvantages

  • The chain is susceptible to maintenance

Can be combined with

  • Motor position: front-wheel motor, mid-mounted motor or rear-wheel motor 
  • Gears: derailleur gears or hub gears

Open chain case

An open chain case is very light, but this is offset by the fact that it does not offer the chain any protection at all. This means that the chain will need a great deal of maintenance in view of the fact that it is exposed to dirt and moisture. The lack of a cover means that you risk getting lube stains on your clothing.

Advantage

  • The chain guard goes with a derailleur

Disadvantages

  • The chain case does not offer any protection to chain or your clothing 
  • The chain is susceptible to maintenance

Can be combined with

  • Motor position: front-wheel motor, mid-mounted motor or rear-wheel motor 
  • Gears: derailleur gears
