Installing the Duluth Cycle Dolphin Battery Downtube Mount is straightforward and requires no drilling or permanent modifications to your frame.
Tools Needed
- Allen wrench/hex key set (included hardware may vary)
- Clean cloth (to prep the frame surface)
Step-by-Step Installation
Step 1: Choose Your Mounting Location
Select where you want the battery positioned on your downtube. Consider:
- Cable routing and clearance
- Knee clearance while pedaling
- Balance and weight distribution
- Easy access for charging and removal
Step 2: Prepare the Frame
Wipe down the mounting area to remove dirt, grease, or debris. This ensures the rubber pads grip properly and protects your paint.
Step 3: Position the Rubber Pads
Place the soft rubber contact pads on the mount. These pads:
- Protect your frame's finish
- Conform to round or oval tube shapes
- Prevent slipping and rattling
Step 4: Secure the Mount
Position the mount on your downtube and tighten the mounting hardware evenly. The mount should be snug but avoid over-tightening, which could damage your frame.
Step 5: Install Your Battery
Slide your dolphin-style battery onto the mount's rail system until it clicks securely into place. Test that the battery locks properly and doesn't wobble.
Pro Tips
- Upside-down mounting: If you need extra clearance, the battery can be installed upside down
- Test ride: After installation, take a short test ride to ensure everything stays secure
- Check periodically: Inspect mounting hardware occasionally to ensure nothing has loosened from vibration

| Battery wobbles | Ensure mount is fully tightened; check rubber pads are properly positioned |
