DIY Homemade Rocker Plate | Cheap Indoor Training Upgrade

[@gcntech]

Would you ever try to make a home made rocker plate?

[@supernoodles908]

If one tennis ball each side is still too much resistance, you could also move the tennis balls just closer to the hinges. They'll have less leverage and will be easier to compress :) picture a nut cracker, easier to crush closer to the hinge Another than you could do, is paint line markings to make sure the position of the balls each side is the exact same :) Fun build

[@nialltracey2599]

Judging by the comments, I think there'd be a fair amount of interest in doing a bit of analysis on the vibration-dampening effects of this. I'd be interested in hearing a comparison of 1) acoustic noise reaching rider/housemate's ears 2) vibration transmitted to saddle and handlebars 3) vibration transmitted to floor (and possibly therefore on to downstairs neighbours). Obviously this all depends on the properties of the floor you're on, so I would repeat the measurements on a concrete garage floor and a typical upstairs bedroom floor. I'd also be curious as to what happens if you just stuff the platform with a couple of dozen tennis balls so that there's no tilt, but just sound absorption. I'm actively considering making one of these myself, but I'm considering making it a rectangle big enough to put under a set of rollers; obviously I wouldn't want my rollers tilting (express ticket to A&E, that!), I'd just be wanting to use a suspended platform to prevent vibration being transmitted downstairs.

[@supernoodles908]

@@nialltracey2599 I know it may sound simple, but put it on a think rug. It'll really absorb upper vibration from being transmitted to the floor and house. And for the top plate you can use acoustic gel pads. They're good for audio reduction

[@ianfurqueron5850]

Yes - quite interested. I have the Wahoo Climb that I'd mount as well. One change I'd add is to make the rear perpendicular to the center line and add a pair of fixed wheels so you can lift up the front end and roll the whole thing around like a hand truck.

[@nialltracey2599]

​@@supernoodles908 oh yes, certainly -- the more different softnesses of absorption you've got, the more frequencies you'll manage to squash. My main point was that people in the comments here are already talking about noise, even though that wasn't discussed in the video. There's definitely enough interest in the topic that it would make a popular (and relatively easy to make) follow-up video. Personally, I already have a lot of soft dampening under my turbo or rollers when I get them out -- foam underlay, soft carpets, a layer of old corrugated carboard and rubber carpet protectors on top. That deals with the high frequencies, so I wonder if a tennis ball suspended platform would get the low frequency roaring out too. However, I'm aware that there's a chance it'll trade mechanical transmission for acoustic transmission: The top plate may act as a soundboard, sending the vibration out into the room as increased sound, but stopping the floor vibrating as much and bothering people downstairs.

[@molhuwmartins9723]

Arrived as expected with all parts intact, also included two hex keys for assembly. kzbin.infoUgkxwOUUBdw8-88Iu4QnQS7q6b2NwZkHiYVl Had to adjust mine slightly to fit my bike, this was easy enough with instructions. I bought it to train with my track bike and found it to have resistance similar to climbing a slight gradient. Takes a while to learn to balance but there is plenty of guidance to help on the internet. Edit: There was more resistance at lower speeds because of the number of contact points but at higher speeds it is much easier as you don’t have to contend with drag.

[@hotcakes1117]

Alex's presenting skills are getting better every week

[@supernoodles908]

Yeah, he was slow to get there but it's great seeing him more comfortable

[@jhessieboy]

Exactly my thoughts. He looked so stiff when he was introduced on the tech show. So proud of how he has grown. Hahaha

[@jbratt]

Comfort comes from practice. All the presenters improve so much over the first year or so. I don’t think any of the presenters have a broadcasting background. It’s fun to see 👍. I like what GCN does. They take enthusiastic bike people and turn them into broadcasters and not the other way around. That way it’s genuine.

[@itsmark3824]

Yeah I was thinking the same. He just took a couple of vids to get comfortable and confident, which is completely understandable.

[@General_Crock]

I think he is the best now, and his topics the most interesting. IMO of course, which also should be yours, lol!

[@fithdor]

I have been riding on Zwift now for about 6 months and slowly dropping the weight and getting in shape. As my rides have gotten longer, I started noticing the need to improve my overall comfort and started looking at rocker plates, but was not impressed with the price. This video hit just in time. This past weekend I modeled a home built rocker plate off of this example. Been using it for several days now (about 5 hours riding), and it works great! Was a little over $50 to make (good plywood is not cheap). Being a very big guy, I did use a total of five hinges, three under the trainer and two under my front riser. I figured that was clearly the weak/stress point of the model so I over-engineered a bit. I also am using three tennis balls on either side, and this works well for my large size. I am looking forward to being able to reduce the number of tennis balls as my weight keeps going down. Thank you GCN and Alex for another great and very useful video! And yes, I wear my GCN kit out on the virtual road.

[@aub8670]

Love these new DIY videos. Some step by step "paper" instructions would be a great addition.

[@itarry4]

Yhea a pdf plan to Download from a link would be easy.

[@stanleyuk1]

Watch it , make your own notes and do it. I’m nearly done mine. As I didn’t have such a long board I I’ve done separately front and back. Hope it works well when finish.

[@JanHolgerOlof]

This was NOT the platform I was expecting a turn it up to 11 from. What an absolute legend, Alex!!

[@JackATAK11]

I made a DIY rocker plate with skateboard trucks. I wish it looked as sleek as yours but it does the job! It makes riding feel more natural / makes me engage my core more and takes the strain off my frame.

[@jshepard5840]

So a few things everyone should know if they haven't yet done the research: The AXIS upgrade kit (cost: $80 US) is only available for the most expensive Wahoo trainer, the KICKR. It's not available for the CORE or the SNAP, so tough luck for those of us who didn't spend top dollar. Also, while most of the reviews for the AXIS kit are good, several reviewers say it didn't make much of a difference at all, probably because their trainers were on carpet or a thick mat. Lastly, while this build for a home made rocker plate looks good, you can find literally hundreds of online builds complete with detailed plans online. I plan on building my own, because as we all know, sitting static on a bike on a trainer leads to a sore bum way sooner than would happen outdoors.

[@nickd5367]

Nice. This is a great series Alex. If you want to increase the amount of rocking movement, once you’re down to the minimum of one ball each side, you could also move the balls closer to the centreline to reduce the moment arm and hence the self levelling torque (assuming there’s minimal flex in the plywood).

[@JackRay]

Not only a great cyclist, but a pretty decent carpenter... Well done! 👏🏼👏🏼👏🏼👏🏼

[@neilkett8230]

Made one of these today with my 11 year old daughter, school is closed so we treated it as a woodwork / tech lesson, she had a blast and said it was the best tech lesson - ever! Gives movement to the bike so that it takes some of the strain off the frame of the bike from the turbo setup and feels a little more real, also takes some of the strain out of the body so less soreness and stiffness from a ride AND it's so much quieter!

[@TheWaxChainFanClub]

Much respect to the OSB workshop. Very smart.

[@jackwhite8988]

already built one.. they are amazing!

[@martinspiegl3986]

Thanks for this incredible vid. I am always annoyed by the noises my hometrainer makes. Seems like this has an end now

[@lwittrock1]

Alex, excellent job on that DIY rocker plate!

[@Choedron]

You do not need hinges. Just place some tennis balls down the middle, as well as the other ones, an zip-tie the ends of the two rocker plates together - preferably the thick zip-ties. You might want one extra zip-tie, in the middle, of this kind of long rocker plate. And the new rocker plate will work great. And drill some 35 mm holes, which you round the edge of with a router, where you want the tennis balls to be. That way they stay in place.

[@TheDarryn007]

The plates will roll without a fixed pivot point.

[@vikingcove]

@@TheDarryn007 "And drill some 35 mm holes, which you round the edge of with a router, where you want the tennis balls to be. That way they stay in place."

[@patty109109]

I’m doing an all tennis now. A better size may be 2”, and the holes can be rounded with a sanding tip on a rotary tool such as a dremel. The hinges remove *all* upward and forward movement, tennis balls alone allow movement in all planes. All planes will be more comfy. I have no idea if there is any measurable power loss.

[@philipplorenz9485]

Alex is a great add to the GCN Team. I really like his enthusiasm for DIY! This is also one of the little things that I missed on GCN, the eye on us ordinary guys with an ordinary budget... So keep on with this good work Alex! Will there be Pt 2 of your Workshop video? ;-)

[@GCNalex]

Thanks Philipp, Ep2 for the garage build will be on its way to you soon! Keep an eye out, glad you are enjoying the vids!

[@AdamBoothUK]

Made mine from a kitchen worktop off cut and about £15 worth of hardware. There’s lots of inspiration online, including a FB group for rocker plate builders. A fun project if you don’t have hundreds to spend on your training setup.

[@MrJhockley]

A few small squares of 2inch rebond foam under each contact point. Took 1 minute to make and install.

[@sshapiro112]

Great idea. I'm definitely trying this before building any kind of rocker. I like the smaller footprint of the trainer w/o a rocker

[@sunratchanonobama4267]

Thank you for this video. I will do it.

[@ijdicer]

Looks great, think this is a project for after xmas

[@Ad-my9kg]

If you want more movement I think you could just move the balls closer to the centre line.

[@SignorLuigi]

Just make sure you don't put your balls so close together that they get pinched by the...ahem..."Rocket Ship."

[@mistagregory]

That's what she said

[@Wheels419]

Absolutely love Alex’s diy skills. Super thumbs up!!!

[@bikemirror6620]

Gcn needs to update/upgrade this rocker plate further

[@Calum_S]

Bonus like for having a dog in the video.

[@ajack3380]

This looks great and I’ve got the parts to build mine in the next couple of days. My plan is to secure large furniture foot cups to the lower board and sit the balls in those. Should stop them moving, but the balls are loose so I can swap them if they lose their compression.

[@110markb]

My version is even more cheapskate. My Wahoo V5 sinks into the Wahoo mat so it looses some of the side to side motion. I cut in half an ex army foam bed roll, one piece width ways under the mat under the feet and one longways under mat under the front wheel. You get a lot more lateral movement. Also I added a Lazy Susan bearing to a piece of ply with some rubber on top to allow more side to side motion at the bars. Combined with a Ram X mount to hold my phone I have a steering set up for the mountain bike route on Zwift....

[@BruceHaskellEventing]

Great video! Build idea...DIY fans system that increases with bike speed?

[@GCNalex]

As in mechanically driven? The wahoo headwind fan already has that feature using speed or HR

[@stevepittman2735]

[@michaelnee1987]

You could also use firmer / softer tennis balls depending on how firm you want the suspension to be.

[@supernoodles908]

You could also move the tennis balls just closer to the hinges. They'll have less leverage and will be easier to compress rather than buying different tennis balls :)

[@hotcakes1117]

Haha, you weren’t the only one. I just didn’t want to say it 🤣🤫

[@RagingCondor]

Great idea! The fact that all the forces goes through the hinge, with the weight of top plate, hometrainer and rider 'hanging free', makes me a little nervous. Every jerk and swerve tugs a little at the screws. Anyway, maybe it's not going to be a problem, but I'd keep an eye on the screws and hinges. I love the tennis-ball solution and the simplicity of the build! When I get a hometrainer I'll most definitely make a rocker plate, very inspiring project Alex!

[@nialltracey2599]

Or build it with a series of wooden strips (eg skirting beading or pine moulding strips) on the base plate, running parallel to the centre line. These would not only make it easier to set the distance, but they'd also prevent the tennis balls squirming their way towards the centre line as your ride progresses, which is a distinct possibility if you're using it for an extended period of time.

Interesting. This might relief the stress on the bike frame, at least partially, which is the most important thing here.

[@Chader9]

Yes, I have no proof, but it is likely to reduce side loading when compared to hard efforts on a rigid trainer. Allowing some degree of freedom and placing that balance and control into the rider likely reduces the loading into the bike.

[@rangersmith4652]

My indoor setup sits idle most the year, so spending a lot on a rocker plate makes no sense. I has a tiny bit of natural "rock," but it would be interesting to see how something like this might enhance the experience. I can see one drawback right away though; unless I include some extra width on the non-drive side as a step, that added height and "offset" will make getting on and off somewhat tricky.

[@floydie9255]

Did you compensate for the offset weight of the Kickr? I had to add a 4kg weight on the right side on my rockerplate setup, otherwise the plate leaned over to the left (when looking from the rear)

[@Chader9]

Adding a counterweight is a good idea. It helps make sure the leaning forces to each side are equal and the deck stays nicely level too.

[@monty2078]

@@Chader9 not a problem with Tacx Neo asthma are symmetrical.

[@Chader9]

Sure. The Neo and any other trainer that is balanced already (without a heavy flywheel offset to one side) won't need or benefit from a counterweight.
