How do I speed up my Shimano Nexus 3?
The Shimano Nexus 3 speed does not require much maintenance as it is encased in a sealed unit. However if there are problems in changing gears, the gear shift system can be adjusted. To adjust, select the middle gear (2nd gear) on the controller then loosen the lock nut on the gear, and turn the adjustment knob.
How does Shimano Nexus 3 speed work?
Three speed hubs use a planetary gear system to achieve a gear ratio between the sprocket and the wheel. In this gear system the sun gear is fixed in place while the planet carier is rotated. This causes the planet gears to rotate which in turn causes the ring gear to rotate. The rider selects a speed using a shifter.

What is 3-speed internal bike?
3-speed bikes are the minimalist version of multi-geared bikes. Like a single speed bicycle, they are reliable bikes that have a simple aesthetic and low-maintenance design. An internal hub houses the mechanics, which means its unexposed parts are protected from the elements.
Is 3-speed bike enough?
For most people, a 3-speed bicycle will offer enough — particularly if you’re looking for versatility. A 3-speed will handle your everyday city streets, and they can make inclines and descents easier. If you’re looking for extra speed or off-roading capability, higher-speed options are a better fit.
How do you use the gears on a 3-speed bike?
You shift gears by sliding the shifter on the handlebars. On most bikes, this shifts the chain onto a different sized ring. On three-speed bikes, the gears are inside the hub of the wheel so you don’t see them. Downshifting means going to a lower gear, and upshifting means going to a higher gear.
Can a 3-speed bike go up hills?
EDIT: many 3 speeds are geared too high, with 2nd being a flat-ground gear. On mine, I installed a larger rear sprocket so that 3rd is about right for flat ground, and 1st and 2nd are for whatever combination of climbing, accelerating, and headwinds. 10/10 would recommend.
