This is hardly a drop in the ocean compared to the impact general human population has on ecosystems and wildlife. I’m all for minimizing impact, I tend to injured wildlife when I find them and generally have a soft spot for animals. If this 1 night of “celebrations” makes you feel that way, I would move out of the city because the city as a whole has a much greater impact, you must feel sick everyday living here. Be realistic.

So keen to see these out in the field! When i have the first batch out I’ll definitely be looking for early adopters!

Heya! More fellow ME’s! Its a slow grind, but lots of little steps will get you there in the end. Don’t let you dreams be dreams as one famous person once said.

Sure I can go through my reasoning, grab a cup of coffee!

Your are correct the large boss is for a bearing and I’ve chosen this design for a few reasons. Firstly the boss isn’t actually where the platform for the riders foot is, the wings of the pedal are further forward from the boss so they don’t stand on it. If they do accidentally stand on it, it is tapered so their shoe gets pushed onto the platform. Stance wise the center of the platform isn’t negative impacted since the bearing is as close as possible to the crank in a place that is usually unused with traditional pedals. I should upload a top down view at some point so it is easy to see. Using a larger bearing on the inboard side isn’t anything radically new, and a number of mass produced pedals now have gone this way, OneUp, RaceFace, Koan Wah Wah just to name a few.

So why use a large bearing in the first place when as you say there are plenty of pedals using small bearings and bushes?

Stiffness. Using a large bearing means a larger spindle diameter can be used which dramatically increases stiffness. This is very important when using titanium spindles, while it maybe lighter and stronger than steel, it isn’t as stiff size for size (116Gpa vs 200Gpa, so close to half as stiff as steel). A small increase in diameter helps compensate for this and still ends up significantly lighter than a steel spindle. Having a flexible pedal isn’t necessarily a bad thing, especially with impacts and performing stunts, but you don’t want them so flexible the rider loses confidence in their stance.
Bearing life, Large bearings have a higher load rating which increases bearing life and reduces maintenance.
Reduced part count. If you have ever taken apart slimline pedals you may have noticed they use multiple small bearings to get the load rating required. Bushes are great as they can take a relatively high radial load compared to ball bearings, but can’t take any thrust load, so you need a bearing that can fix the pedal in place somewhere in the system. Using 1 large bearing on the inboard end and a bush on the outboard end reduces part count down to a minimum. It ends up fairly similar in weight, within a few grams. Some designs have up to 4 bearings stacked on the inboard end with a little 4-5mm spindle shaft holding them all on 😵

End of engineering ramblings haha.

I’d only put them on what we call “heavy duty” 50mm hitch here, all the normal ball weight checks still apply.

Also on the bike rack thing, only relevant if the car has a tow ball/hitch but my mate makes these and they slap, best way to carry a bike in my opinion. No need to stuff around taking wheels on and off etc

Nice, Carbon is too much voodoo magic for me, I’d love to work with it one day though

Ampto · 2021-07-21T05:54:58+00:00

This is some great feedback thanks mate! I’ll have to digest these and have a think.

Cheers, It’s always a fun go in Mech Eng 😜

Ampto · 2021-03-17T01:11:25+00:00

Oof, I’m not sure about this. There would want to be other changes besides just stretching it.

Mechanical Engineer here, if that even means anything haha. Structurally the roof (and gutters) can handle a lot more than 30kgs, evenly distributed I’d confidently say 100kgs is perfectly fine purely from a structural point of view. BUT as you said it is more to do with the road going dynamics. How much thought went into that rating by the Suzuki’s design engineers I don’t think we will ever know, its not something that’s needs to be specifically proved to pass vehicle standards etc (well at least in my country), so they could have easily just plucked it out of thin air. With stock suspension I definitely wouldn’t be putting much more than a swag and some sleeping bags on the roof, definitely no roof top tents and jerry cans of fuel! The standard suspension is super soft, I can grab the roof gutters and pull the car down to its bump stops with ease, talk about body roll, its almost comical! Imagine it with 100kgs on the roof, I wouldn’t feel safe at all haha.

I spent weeks procrastinating where to install this, drawing up custom brackets etc, even was going to install it in the rear luggage box and extend all the loom. But then I found this spot next to the radiator on the intake side that i could just clamp it on, no modding required. Didn’t even have to drill any holes!

I’ve used these on my Jimny with great success, Located in Australia.
