Installation

The Following Numbered Photos Provide Installation Guidance on Left Side of Bike

1. Hybrid cruiser bike is shown with BTL installed, left side, close the rear axle. The outer clamp is close to vertical with the flexible coupling on the bottom. Note the mast is directed up and forward. Rotate the clamp on the bike frame so the clip end of the mast is at the dog's shoulder height with the bike vertical.
   
   
2. Shown is the most common placement of inner clamp clamping across 2 rounded frame members. Note; the  inner clamp bolts are above and below the 2 frame members. If these members are too far apart, put the long bent end of the inner clamp up to capture the upper frame member.
   
   
3. Clamping across the axle mount with bolts above and below is the second most common mounting arrangement. Note: On thin frames the bolt ends must not protrude beyond the end of either knob. Add washers under the knobs to cover all the bolt threads. Also, the inner and outer clamps are covered to preventing slipping and to protect the bike's finish.
   
   
4. Thick frame member mounting shown with the supplied washers (black) on both bolts between the inner and outer clamps This is done for the bolts to reach across the thick red frame into the knobs.
   
5. Disc Brake Bike Installation:  The simple trick with disc brakes is to first slip one bolt out of the inner clamp.  Then slip inner clamp up between the disc and frame just ahead of the axle.  with this bike frame type, the inner clamp is slipped with long end up to clamp the seat stay part of the frame. Note; during tightening, lift the clamping unit for securely clamping the upper cross member.
   
   
6. BTL fully installed on rear disc brake bike. Note: once clamped, make sure there is clearance between the inner clamp and the disc brake.
   
   
7. The BTL comes set for left side use with medium size dogs with the outer clamp vertical. The outer clamp can be rotated before tightening to adjust height. If the outer clamp cannot be rotated far enough, release the coupling by adding regular 70% rubbing alcohol all the way around inside the coupling as shown. Let stand at least 6 minutes, grip the clamp in one hand and coupling in the other, then twist hard, with knobs removed, to release the outer clampfrom the coupling.    Adjust  so mast meets the dog's shoulder height with the bike standing vertical. Allow the alcohol to evaporate before use to lock coupling in place. See video instruction.
   
   
8. The BTL comes defaulted to left side.  For right side installation see the Accessories tab for pre-adjustment and right side mounts.
   
   
9. The BTL, primarily for bicycles, also will attach and work great on mobility scooters, chairs and other personal mobility devices.  For these special needs applications, please contact us prior to purchase for specific instructions for your device.  Emailing photos and links to the equipment is a great help and saves time.  Go to the photos tab to view some of these special needs application and installations.
