I knew it would work.....

(using a Saris dropout bracket costing $45)

I like it! Now all you need is the Rhino SQR's rear wheel tie down mounted on your spoiler (or an occy strap for a more cost effective solution) to hold the rear wheel in place and you're laughing. :) Another option would be to get your passenger to hold the bl**dy thing. :D :D

How do you control the accelerator from up there though?

I can still zip out the rear window and get the forks to reach the bracket, so the bike gets wet but I don't.

Oi!!! That was my idea back on Aus-Car (MX5 Forum) :D

I see you've swapped out the style bar for that one, wouldn't of worked on the SB.

As said above, the only downside is that you'll have to secure the rear wheel down, and if it were me I wouldn't rely on the strength of the spoiler to hold the rear wheel down in the event of an accident. I could see the bars making a mess of the passengers (wifey) head if that happened.

Also, your pedals look precariously close to the boot lid, especially if the spoiler was the flex with a bump...I know how little compliance there is in these MX5's suspension too.

Yes - the idea came from you..... but I applied it. :D

I've always had that particular style bar , but you could also do this with the twin hoop style by using the central brace as the mounting point.

There's about 1 inch of pedal clearance, but I figure I can use the trick the elite triathletes use and hook a couple of rubber bands between the pedals and the rear drop out to hold them level in transit. I'm still working on a couple of ideas as to how to hold the rear wheel down - just wait till the new QTS season - you'll get to see if it has worked :D

Knowing how well anchored and strong those "plastic" pseudo-spoilers are, I'd be pretty weary of that solution. It may be fine sitting in the driveway, I wouldn't do it if it had to be taken on the open road on safety concerns.

It's actually a full solid fibreglass rear spoiler, mounted by 4 HT 6mm bolts through the boot lid and into metal captive threads built during molding into the base of the spoiler. Weighs probably as much as my bike does actually.....

Ok, that sounded better than some of those spoilers I've seen. But still, the weight of your bike is only relevant for static loading. Dynamic load at 80km/h will be significantly greater.

I am surprised there are no dedicated bike carriers made for the MX5. Surely there are certified products out there, right?

Just the standard towbar mounted bike rack, or the hanging rack that goes on the back of the car.

I didn't like either.

Anybody remember how Pugsley hung his bike off his MX5?

Hmmm, drive an MX5 somewhere for a ride, best o' both worlds :D

Replace the drops with a TT aero base bar and you have a second spoiler - the handling would be SO much better...

To all the doubters - this is a great way to carry the bike on the 5. :D

I finally tested it this morning - had to drive to the morning ride due to another outing straight afterwards, that didn't allow time to ride home and change.

Basically it required a flat nylon strap looped over the rim at the front, under the spoiler, and back over the rim at the back and tied off. The spoiler is quite heavy and fully fibreglass, so it doesn't flex. That held the rear wheel solidly in place. By moving the front dropout clamp towards the middle of the car, it places it in such a position that the front dropouts can be easily clamped with the roof up but the rear window zipped out (as is the case on early MX5s. The front wheel sits nicely on the parcel shelf behind the seats, roof up or down.

On the (cold) drive in I had the roof up and the heater on, and on the drive home I had the roof down and the sun on my face, all the while with the bike firmly in place above me.

:D

The heat from the exhaust won't do his carbon rims much good. :wink:
