How to Assemble the SRPNT by Throne Cycles (Step-by-Step Guide)


Tools & Supplies You’ll Need

  • Allen wrenches: 4mm, 5mm, 8mm
  • Open-end wrench: 14mm
  • Torque wrench
  • Dead blow hammer or mallet
  • Small flat screwdriver
  • Loctite (blue threadlocker)
  • Suspension fork air pump (for KKE forks)
  • Bike grease
  • Zip ties (not included)

Unboxing & Preparation

  1. Open the box and remove components:
    • Save zip ties and packing materials for reuse.
    • Remove: handlebars, front wheel, charger box, seat, display, fenders, and peg hardware.
  2. Locate your keys:
    • Keys are in a small box inside the main packaging.
  3. Remove battery:
    • Pull seat release latch and remove seat.
    • Push the rear latch button and pull battery toward the rear of the bike.
    • Unplug battery connector and set battery aside for charging.
  4. Charge the battery:
    • Use the included 84V 9A charger.
    • Plug battery in and verify charge level (typically ships 70–80% charged).
    • Avoid placing the charger near your filming area—fan hum is audible.

Install Front Wheel

  1. Remove axle:
    • Loosen pinch bolts on the fork using 8mm Allen.
    • Use a dead blow and small screwdriver to tap the axle out.
    • Do not hammer the axle directly—threads can be damaged.
  2. Prepare axle and spacers:
    • Lightly grease axle and rubber edges of spacers.
    • Position one spacer into left fork leg.
    • Insert wheel with brake rotor aligned into left fork leg.
    • Slide axle through, add second spacer on right, and push axle fully in.
  3. Tighten components:
    • Finger-tighten axle bolt with 8mm Allen.
    • Alternate tightening pinch bolts evenly, then snug the axle bolt.
    • Torque all bolts to spec.

Inspect & Secure Rotors

  1. Check both front and rear rotors:
    • Confirm they are 3mm thick with Torx or hex rotor bolts.
    • Remove each rotor bolt one at a time, apply blue Loctite, reinstall and torque to spec.
    • Do this for both front and rear to prevent future vibration or loosening.

Install Handlebars & Controls

  1. Install throttle and brake lever:
    • Slide throttle onto handlebar before installing bars in stem.
    • Lightly snug bolts with 4mm Allen. Finalize throttle angle and snap-back function.
  2. Mount handlebars:
    • Insert into direct-mount stem and hand-tighten the four clamp bolts.
    • Adjust bar position to your preference (stem has 3 adjustable positions).
  3. Install reflectors:
    • Thread into sides of fork legs or handlebar area.

Brake Switch Connection & Setup

  1. Locate and connect brake motor cutoff switches:
    • Remove plastic spacers from brake connectors.
    • Match HEGO-style male/female connectors and align pins properly.
    • Click securely into place—do not force.
  2. Optional:
    • Disconnect motor cutoffs if you prefer throttle control during aggressive riding or wheelies.
      * SRPNT does not yet have app-based toggling for this feature.

Install Front Fender, Chain Guard & Display

  1. Fender and chain guard:
    • Use supplied bolts (4mm Allen) with Loctite.
    • Do not overtighten; secure just enough to hold in place.
    • Chain guide is metal with a plastic liner—ensure snug fit.
  2. Display:
    • Use included 4mm bolts and aluminum mount.
    • Plug in using keyed connector—listen for two clicks.
    • Leave slightly loose if you want to adjust visibility while riding.

Install Pegs & Frame Brace

  1. Footpeg Installation:
    • Use included locking nuts—no Loctite required.
    • Consider your preferred peg position (middle by default).
    • REV Rides offers upgraded pegs and colors.
  2. Frame Brace Positioning:
    • Three positions: front, middle, rear.
    • Rear is recommended for extra support if pegs are set forward.

Battery Installation

  1. Insert battery:
    • Slide in from the rear until fully seated.
    • Connect battery leads using keyed plug—press until latched.
    • Lock the battery connector using the side button.
    • Replace underseat port cover and seat.

Zip Tie & Cable Management

  1. Secure cables:
    • Zip tie throttle and brake lines to prevent movement.
    • Tuck wiring behind metal cable guides where applicable.
    • Clip zip tie tails and rotate them out of sight for a clean finish.

Final Steps Before Riding

  1. Remove protective plastics and stickers
  2. Check tire pressure
  3. Check chain slack and lube the chain
    • Clean and re-lube every dirt ride or weekly for street use.
    • Expect chain stretch during the first 100–300 miles.
  4. Check spoke tension after 50 miles
    • Refer to manual or upcoming REV Rides tutorial for truing wheels.
  5. Adjust suspension
    • Front fork is adjustable KKE air fork (use proper shock pump).
    • Rear shock is preload and rebound adjustable.
  6. Double check throttle snap-back and brake pressure
