I guess I won't know until my trailer falls off the bike, but it is more likely that I will give out before this connector does. ### ⭐⭐⭐⭐⭐ Strengthening the Hitch *by A***N on July 30, 2014* After a year of pulling approximately 100 lbs averaging over once a month, I found I needed to add strength to the hitch as it began bending. I first made a prototype gusset out of 4ct building tie down straps (~ 3/16"T total) then went to a solid metal flat bar 1-1/4"W. I cut 5"L and rounding corners. I drilled 2ct 13/32" holes for the axle and hitch hub mount. A stainless steel 3/8"d x 3/4"L bolt with lock washer to mount hitch in which I also cut out for the key way washer that comes with the hitch using a metal cutting saw blade. A # 8 stainless steel 3/4"L bolt to mount as security to the bike frame tail drilled @ 3/16". 4ct #6 s.s. 3/4"L bolts (2ct top & 2ct bottom) of the hitch drilled @ 5/32" using cobalt drill bits to drill through the bar as also the 5/32" hitch holes (using a metal punch to start the bits cleanly while hub bolted and clamped at center top). Titanium bits can work but have a tendency to break. Keep the bits oil cooled while drilling. Being that I know the hitch is not for industrial use as I use it, for children involved, the gusset is the way to go for added safety. I recently ordered another hitch and again, extremely pleased with the fast shipping. Nevertheless, for the design I give it five stars. ## Frequently Bought Together - Schwinn Coupler Hitch Attachment Compatible for both Schwinn & InStep Bike Trailer, Flat and Angled Couplers for Wide Range of Bicycle Carriers, Trailer Sizes, Models, Styles, Hassle-Free Installation - Titanker Upgraded Bike Trailer Attachment Coupler for Instep & Schwinn Bike Trailers, Bicycle Trailer Hitch Bike Cargo Trailer Coupler - Schwinn Rascal Bike Dog Trailer, Carrier for Small and Large Pets, Easy Folding Cart Frame, Quick Release Wheel, Universal Bicycle Coupler, Washable Non-Slip Lining --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/284767-coupler-attachments-for-instep-and-schwinn-bike-trailers-flat-coupler](https://www.desertcart.us/products/284767-coupler-attachments-for-instep-and-schwinn-bike-trailers-flat-coupler) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-23*
