Just Joe Posted May 7 Share Posted May 7 I think that I may try using the attached bike rack with it adjusted so it rests on the bumper box for additional support. The spare tire bracket is massively strong like other fittings on my 2021 LE2, so I believe that it should work just fine. Since I will need to take off the spare tire cover, I'm going to use a separate license plate lighted bracket attached to the rack. I measured my two standard bikes and their tires will be just above the hinged bumper when hung on the rack. Any thoughts?

Thanks, Joe/769 I think it really depends upon how secure you want your bikes and what the weight capacity is of the rack. I'm not sure how that one actually attaches. My heaviest bike is an emtb that weighs 39 pounds and is well within the capacity of the rack I'm building. However, I love to see things overbuilt and I don't want a bike falling off going down the interstate. I've seen it happen and it does horrible things to carbon fiber frames! Bottom line is I wouldn't trust it with my bikes but that doesn't mean it won't work. There's lots of movement on the back end of a trailer. 3 2021 LE II - Hull 922 - "Ollie Be Back" 2013 Silverado 2500HD Duramax Hugo & Penny Bob & Cash (the pups) Link to comment Share on other sites More sharing options...
jd1923 Posted May 8 Share Posted May 8 @Half Fast Hugo your build is excellent! I'm thinking if I build a mount like yours, I can haul my '03 Honda CRF230 (it's an old man's Honda 250, detuned with electric starter added). It weighs 230 LBS (please those that worry, do not warn me about the weight limit OTT puts on their punny 1 1/2" hitch receiver). OTT has crazy strength built into the rear, with multiple frame crossmembers, etc. It all depends on your GTWR and resulting hitch weight when you add more weight to the rear. Anybody want to buy my rear OEM hitch, that for hull #113 was a full 2" receiver? It's sitting in the loft of my shed since I have no use for it. Loved bicycles all my life, but for the heavy climbs and descents of Arizona, I prefer a bike that can climb a 20% grade with combustion engine power (and an e-bike just doesn't cut it, old but not that old). 1 1 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

MAX Burner Posted May 11 Share Posted May 11 (edited) Actually, I'd consider a Honda Trail 90 or 110 for that rack.... How cool would that be on the dirt with that insanely low gear? It's probably about the same weight as a couple Ebikes, right?

How cool would that be on the dirt with that insanely low gear? It's probably about the same weight as a couple Ebikes, right? Love ya buddy, but you're not getting my old a$$ on a Trail 90! 🤣 Two e-bikes are 150+ LBS, more likely closer to 200 with accessories and keep in mind the rack weighs LBS. My '03 Honda CRF230 (bought barely used in VA late '03, totally rebuilt in 2019, new performance springs, new tires, and much more) weighs 238 dry, let's call it 260 LBS with oil and a full tank (1 gallon gasoline). We have ridden dirt in most of the Prescott NF. Chris cruised a Polaris 600 quad for years, though I prefer 2-wheels. I can make this work. Will post a mod at some point. I do need to measure our current tongue weight and front to back balance. OTT has built the frame structure for this with 7-8 crossmembers rear of the wheels. It would be great! Recently, to test I climbed on the back bumper of the Oliver, jumping up and down hard with myself of 225 LBS. It was solid as a rock, though a bike rack would be further back, a longer lever per the center of the trailer wheels.

jd1923 Posted May 11 Share Posted May 11 BTW, I would ONLY think of this kind of HD bike rack, mounting a relatively heavy dirt bike, AFTER I do some of the upgrades that @MAX Burner has completed; Alcan Springs and 5200 LB axles with 12" brakes and perhaps Monroe 555025 shocks if it's determined they would be a good upgrade and fit. There's quite a bit of money in doing all this and it makes sense to do this work all at the same time, for me time is TBD. Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

Had we not planned to attend the owner's rally, we probably would have lived with the 3.5k#-ers for a while. But here's a consideration - the D52 Dexters (or the older D44's and D35s for that matter) are custom cut to OTT width specifications (they're only approx. 62.5" flange-to-flange). I suppose one could order an OTT spec'd set of axles from Dexter in Sparta, TN but that could be costly for a single run off. We have not contacted Dexter to learn what the one-off cost/time schedule/shipping costs would be - maybe another owner could do that. Since headed eastbound from NM anyway, we decided to contact OTT directly, and coordinated with Jason Essary to acquire our axle kit. Timing was just right with the rally scheduled for next week. Our approach to the running gear upgrade became a phased approach instead of "all at one time in our shop" primarily due to logistics and cost. Alcan springs first, 5.2k# axles, then shocks (only by happenstance, not planning) - & the Cooper Discoverers only have about 15-16k on them. As far as labor costs, my time is free for me... We ate the cost of travel to Hohenwald because we planned on attending the owner's rally anyway - the entire running gear upgrade worked out well for us. HA!

What you’re doing could be me next year. An OTT visit tied in with the 2025 Rally, get my FWT fixed too like you. Are you doing the CGI Detailing too? I’m getting rather jealous of Casablanca #226.

Just Joe Posted May 12 Author Share Posted May 12 For anyone who doesn't already have a bumper mounted system, this spare tire mounted bike rack is a great option for taking along two standard bikes. There are even holes already in the rack for a license plate bracket. The fully assembled rack was $120, and the license plate bracket and a two-pack of 1" ratchet tie down staps were each $10 on-line. I simply reversed the center mounting plate so that the bottom of the rack would curve toward the camper and rest on the bumper box for additional support. I used the additional staps for additional support, but they really weren't needed. There is a keyed twist lock included with the rack and I'll use one of our cable locks wrapped around the bikes. Our bikes are less than 30 lbs each, so the entire assembly appears to be well supported and secure.

Whoa, Pilgram! 🤣 Did you look at what/where the spare tire bolt is connected? This design has the weight of 1-2 bikes on one (1) threaded bolt! What is it, just a 1/2" bolt? Came back from our last trip and the spare fiberglass housing was loose, the large, winged nut to hold the spare was also loose many turns. This bolt is designed to hold up the spare upright while its weight is held by the frame below. I'm not crawling into the Oliver basement/trunk to see what is supporting the main bolt for the spare, but you certainly should do so before you go on a Rocky Mountain excursion, or anywhere else. It may look good in the driveway but as a seasoned engineer, and 45 years a car mechanic, I'm not seeing it! Do you due diligence. The downside would be your precious bikes and spare tire bouncing down the highway, leaving a hole in the Oliver fiberglass hull the size of the bolt head and washer, or whatever support bracket may be there. To boot, ask anybody here, I'm more the risk-taking person, but I would not risk this! When you lose your bikes, you will not know it until your next stop. Keep on checking, keep that one wing-nut tight. Actually, the tighter you make that bolt, the more likely it will bust the fiberglass. This would drive me crazy! Certainly, I can be wrong, we all are at times. Please let us know what you experience. BTW, welcome to our Forum! God Speed and best wishes.

jd1923 Posted May 13 Share Posted May 13 (edited) I will add that if the total assembly is 60-70 LBS, and you ride nicer suburban roads/eastern Interstates, you should be OK. Keep in mind that in the Jeep picture shown above, the single mounting bolt is mounted to a steel frame, not fiberglass. We just got back from 2 1/2 weeks, from here and throughout SW Utah. We would hit a cattle grate on a side road and even a simple bridge seam on a major US Hwy, and the TV and TT would bounce heavily! You try to see them coming but it will look fine and then bounce hard. Edited May 13 by jd1923 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

Just Joe Posted May 13 Author Share Posted May 13 I too was concerned, so before proceeding I crawled into the basement and there is just under a 1'x 3'x 1/4" backer plate that the approximately 1' spare tire mounting plate is through bolted to with 4 - 1/2" bolts. Since the spare tire does not rest on the bumper box when hung on mounting plate (there is a couple inch gap between the tire and the box), the addition of the bike rack actually adds back the support of the Oliver cover by resting on the bumper box. In addition, I added the two ratchet tie down straps to absorb any stress of the assembly pulling away from the camper even though I didn't detect any movement when pulling on the rack. The weight is now being carried by three points (the massive mounting plate, the rack resting on the bumper box, and the angled ratchet straps). We stay on good roads when we travel, but I will still be checking everything regularly. I will update my post after a few trips to report what I experience.

Half Fast Hugo Posted May 31 Share Posted May 31 Well, the bike rack is finally done. Finished wiring it up yesterday and it's lit up pretty well. I ended up using the 1Up license plate holder which has it's own light and added the Curt lights on the back to give it a little more. I couldn't decide if I wanted to splice them together and keep one plug connector so I used a splitter after coming out of the thru hull in case I need to replace one or the other down the road. It comes on and off easy so if I'm not hauling the bikes it's two simple disconnects and the four pins. I'll end up replacing a couple of pins with locks at some point. I can sit on the farthest out rack and it's definitely solid. My heaviest bike is an eMTB at 39 pounds so shouldn't be any issues!

MAX Burner Posted May 31 Share Posted May 31 @Half Fast Hugo - Nicely done, Hugo! Beefy and clean - always a couple of my design requirements. Looking forward to seeing y'all again down the road - we've already got our rally site reserved for next year, FYI. (OBTW: Todd should have his chocks by now).
