Setting Front Wheel Toe-In Angle
Setting Toe In For Tadpole Trikes
(0mm to 3mm recommended):
1. With the trike on the ground and wheels fixed in the straight ahead position, measure from the front of the left wheel centerline across to the
right wheel centerline. See Figure H. Record that measurement.
Repeat the above for the rear left wheel centerline across to the right side centerline. See Figure I. Record the measurement.
The measurement should be the same or up to 3mm toed in.
2. Hint for simple measuring technique: Use a tape measure and hook one end on an inside spoke at the centerline of the left front wheel and
measure to the opposing inside spoke on the front of the right hand wheel. Use the same technique at the rear.
3. To adjust the toe in, loosen the Rod End Jam Nuts (See Figure J) on the Steering Linkage Assembly (7) turn the Steering Linkage clockwise
or counter clockwise. This will lengthen or shorten the rod since the rod ends are right hand threaded on one side and left hand threaded on
the other.
4. Tighten the Rod End Jam Nuts (See Figure J) and recheck the toe in. Re-adjust if necessary.

Fit Adjustment
1. Adjusting Seat and Boom
a. The goal is for your seat (and therefore your weight) to be as far back as possible when your set up is complete.
b. Loosen and slide the #10 Seat Frame Assembly rearward on the Main Frame until in a comfortable seating position. Adjust the seat
angle by removing and reinstalling the #27 Strut Pins into a new position on the Seat Struts if necessary. See Figure T.
c. Loosen the Crank Boom Clamp Bolts and position the boom so that when seated, your knee should be just slightly bent when the forward
foot is in the farthest position. See Figure U.
d. Re-tighten the Crank Boom Clamp Bolts to the specified torque setting.
e. If you cannot extend your leg forward enough, you can then move the seat forward to get the proper fit.
Note: Your chain may need to be lengthened or shortened depending on your final seat and boom position.
Seat struts can be trimmed and re-drilled as necessary to provide a perfect fit.
CAUTION: Never lubricate or wax the part of the boom that goes into the frame. See Figure V.
2. Adjusting Handlebars and Headset
a. Loosen the clamp bolts (1) that secure your Handlebar
Assembly to the steering tube. See Figure W.
b. Carefully loosen the Top Cap Bolt (2).
c. Position the Handlebar Assembly to the desired position
then carefully retighten the Top Cap Bolt (2) only until play is
removed from Headset Bearing Assembly and the Front
Wheel Assembly still turns smoothly. Do not over tighten.
d. Tighten clamp bolts (1) on Handlebar Assembly until secure.
e. Repeat for opposite side Handlebar Assembly.
f. Recheck Handlebar and Headset adjustment after a short
test ride.
WARNING: Make sure that once you have made all your handlebar
adjustments, you have sufficient clearance from your hands to your tires or
wheels and that control cables are secured away from all moving parts.
Failure to do so may result in loss of control resulting in a serious or fatal accident.
