2018 and 2019 RadRover Front Fender Installation Steps:

1. Shift the bike into gear 7, which will make several steps easier (by moving the chain onto the smallest cog of the cassette). 

Step_1.jpg

2. Power off the bike. Ensure the bike is in the off position and use the key to remove the battery. Once removed, press and hold the “MODE” button on the LCD Display Remote until the display remains off for about two seconds (it may flash on briefly). This ensures the power is fully discharged from the bike and it is safe to work on.

3. Install the front fender, which is shorter than the rear fender: 

a) Remove the headlight. Unplug the headlight connector by pulling each side of the connector directly apart. Use a 5 mm Allen wrench and a 10 mm wrench to remove the headlight bolt, front washer, rear washer, and lock nut. Set this hardware aside for reinstalling the headlight.

b) Move the fender into position. Deflate the fender enough to pass the U-shaped metal bracket under the front fork arch. From the back of the front wheel, pass the front of the fender between the tire and the front fork arch so the U-shaped bracket is just in front of the light mount on the fork arch.

c) Bolt the fender and headlight to the front fork arch. Pass the headlight bolt through one washer, the headlight mount, the U-shaped metal bracket on the fender, and into the mounting point on the front fork arch. On the back of the bolt, install a washer and then the locknut. Use a 10 mm wrench and 5 mm Allen wrench and torque to 6 Nm. Then connect the headlight by carefully aligning the pins inside and arrows on the housing and pressing the ends together to fully seat the headlight connection.

d) Move the P-clamp mounting brackets into position on the suspension fork lowers. On the left side of the front wheel, the side with the front brake, take care to not touch the metal brake disc and wrap the P-clamp around the fork lower (below, left). Ensure the mounting bracket runs along the outside of the brake cable. Wrap the right side P-clamp around the fork lower (below, right).

3.d1.jpg   3.d2.jpg   

e) Tighten the P-clamp leaving a gap to ensure both sides are parallel. Insert one 26 mm bolt into one small washer, through the P-clamp end, and thread into the backing nut. Tighten until the gap between the P-clamp end and the side is parallel (as indicated by the orange lines below). Do not overtighten. Repeat on the other side.

5. Install the rear fender per the steps unique to the bike model year by clicking on the bike model steps below. There are a few differences in RadRover rear fender installation between the 2018 and 2019 models. 

2018 RadRover Rear Fender Installation Steps:

6. The rear fender ships with the 2019 mounting bracket installed. Before attaching the fender, swap out the metal mounting bracket attached to the rear fender (2019) with the mounting bracket included in the box (2018):

a) Remove the 2019 mounting bracket from the fender. Use a 4 mm Allen wrench to remove the two bolts holding together the mounting bracket clamp (consisting of an exterior metal piece and a threaded backing plate on the fender’s interior). Remove the 2019 bracket and recycle where possible.  Set the hardware aside for re-installation.

2018_6a1.jpg   2018_6a2.jpg   2018_6a3.jpg

b) Install the 2018 mounting bracket:

i. Orient the 2018 mounting bracket so the eyelets at the end of the mounting bracket bend up towards the top of the fender. 

2018_6b1.jpg

ii. Holding the backing plate in place on the inside of fender, place the exterior piece of the mounting bracket clamp so the holes are aligned, and the mounting bracket is centered in the clamp.

2018_6bii.jpg   2018_6bii2.jpg

iii. Thread the mounting bracket clamp bolts through the exterior piece of the clamp, the fender, and into the backing plate. Tighten securely.

2018_6biii1.jpg   2018_6biii2.jpg   

7. Deflate the rear tire OR remove the rear tire assembly following the wheel removal instructions below:

a) Flip the bike upside down. Set up blocks on which the handlebar grips will rest (to prevent damage to the controls and LCD display) and flip the bike upside down resting on the handlebar grips on blocks and the seat.

b) Remove the torque arm bolt. On the non-derailleur side of the wheel, use a 4 mm Allen wrench to remove the torque arm bolt, next to the axle nut, and set aside for re-installation. 

c) Loosen the axle nuts. Use an 18 mm wrench to loosen the axle nuts enough to allow the rear wheel assembly to be lifted out of the rear dropouts, but keep the nuts and hardware installed (the orientation of this hardware must remain the same). Set aside for re-installation.

d) Unplug the motor connector. Use flat side cutters to snip the zip tie holding the motor connector cable to the frame taking care to not damage to the cable housing or wires and pull the connector directly apart without twisting.

e) Remove the rear wheel. Take care to not touch the metal brake disc and lift the rear wheel assembly out of the dropouts. Note the orientation of the washers on the motor axle for re-installation. Set the wheel aside. Note: Shifting into gear 7 moves the chain down onto the smallest cog on the rear wheel cassette and will create enough slack to pull the derailleur and slide the axle out of the dropouts.

8. Install the rear fender on the 2018 RadRover:

a) Move the fender into position with the flared end/mounting bracket clamp near the back of the bike and the flat end near the chainstay. Deflate the rear wheel enough to align a 40 mm long bolt into the mounting point at the chainstay arch.

2018_8a.jpg

b) Attach the fender at the chainstay arch. Pass one of the two 40 mm long bolts through one of the larger washers and then through the mounting point near the flat end of the fender and through the mounting point on the chainstay arch. At the back of the bolt, install another large washer and thread the lock nut onto the bolt end. Use a 5 mm Allen wrench and 10 mm wrench to tighten part way.

2018_8b1.jpg   2018_8b2.jpg   2018_8b3.jpg    

c) Attach the fender at the seatstay arch. Pass the other 40 mm long bolt through into the
mounting point on the seatstay arch then the U-shaped mounting bracket on the fender. Install a washer and lock nut on the bolt end. Ensure adequate clearance between the fender and tire and use a 5 mm Allen wrench to torque to 6 Nm.

d) Torque the chainstay bolt to 6 Nm.

9. If previously removed, install the rear wheel on the 2018 RadRover:

a) Move the rear wheel into position in the rear dropouts taking care to not touch the metal brake disc. Place motor washers back into their original orientation, ensure the brake disc slides in between the brake pads in the brake caliper, and the axle is fully seated in the dropouts. Note: Aligning the chain on the smallest cog of the rear wheel cassette will create enough slack to pull the derailleur back and slide the axle into place. 

b) Tighten the axle nuts. Ensure the axle is fully seated in the dropouts and use an 18 mm wrench to torque the axle nuts to 40 Nm. Note: leave the torque arm bolt uninstalled for now.

c) Plug in the motor connector. Carefully align the pins inside the connector and arrows on the connector housing and press the two sides directly together without twisting to ensure proper connection.

d) Zip tie the motor connector cable to the cable guide on the chainstay. Use flat side cutters to trim the excess zip tie

10. Attach the mounting bracket to the 2018 rear dropouts: 

a) On the left side of the bike, take care to not touch the brake disc, and pass a 23 mm long bolt  through a larger washer, the fender mounting bracket eyelet, the torque arm bolt hole, and thread the bolt into the torque arm bolt mounting point on the rear dropout. Use a 4 mm Allen wrench to torque to 5 Nm. 

2018_10a.jpg

b) On the right side of the bike, use a 4 mm Allen wrench to remove the bolt on the derailleur bashguard that is closest to the derailleur. Pass a 23 mm long bolt through a larger washer, the fender mounting bracket eyelet, the bashguard mounting point, and thread the bolt into the mounting point on the dropout. Use a 4 mm Allen wrench to torque to 5 Nm.
