Speed Control System

The Speed Control System is made to help you travel through 

various terrains and conditions easily by adjusting based on the 

strength of your pedaling. 
The Speed Control System is comprised of a Derailleur, a Front 

and Back Fender, a Chain Plate, a Flywheel, and Shift Cables.

NOTE: Do not backpedal when shifting gears, this could potentially lead to the 

a failure of shifting and the chain falling off. Do not change gears substantially, 

always shift gradually and in accordance with the speed at which you are cur-

rently travelling. Shifting up or down multiple gears at once will lead to more 

rapid wear and tear of the Speed Control System. The chain, fluted disc, flywheel, 

and Derailleur should always be washed, wiped, and oiled appropriately.

Derailleur

The Derailleur is a 7 speed dial type, posi-

tioned on the right side of the handlebar. 

When the large trigger is pushed, the gear 

shifts to a lower gear, while the button 

at the bottom of the Derailleur shifts to a 

higher gear. Lower gears are preferable 

when riding up inclines, while higher gears 

are great for downhill speeds.

The Derailleur is attached to the Back 

Fender. When the shift cables are too loose 

or too tight, or if the speed controller does 

not work properly, the H and L Bolts need 

to be adjusted.
To adjust the H Bolt to its proper position, 

adjust the chain so that it’s on the smallest 

flywheel, then turn the H screw so that the 

guide pulley with the smallest gear is on 

a straight line. To adjust the L Bolt, set the 

chain to the largest flywheel, then turn the 

L screw so that the guide pulley with the 

largest gear is on a straight line (as shown 

in 

Figure 1

).
