Cooling sys needed for slow riding

I saw this guy blogging he jury rigged an electric fan and a 9V battery on his helmet for cooling.

My afternoon commute home is becoming pretty brutal. I ridie too slow to get enough air flow into the helmet.
And I'm about to quit unless I can find a solution that doesn't break the bank.
And those stop and go traffic.
I mean, lately 105 heat index...not much wind to help cool.
I mean I'm prorbably doing 10 mph. Yeah, I'm slow, wide tires...heavy bike.

I really need to do something to make to commute for comfortable.
I mean, riding should be fun, not a torture.
Or I won't make it.

Bikes: The same GT Outpost Mountain bike I've been riding since 1996, although I modify it throughout the year for commuting, touring, and recreational riding.

You're probably thinking you want some type of fan, but I think a more practical solution would be to carry a spray bottle filled with water and just spritz your face during your commute. My job during the hot summer months is setting up outdoor concerts and I find a simple blast of water in the face - and maybe on my neck - can change my whole attitude instantly.

I have seen a baseball cap with a solar powered fan in the brim, cut that off and glue it on to your helmet?

I feel the heat too. In Atlanta itís only in the low 90s now, but the humidity is in the high 90s.

Yeah, itís awful, but as long as Iím well hydrated before leaving work, Iím ok. Iíve lived in the Southeast my whole life, so I think Iím used to it. This is about the time of year I start bringing two water bottles, Iíll drink one to get me brought the 10mike commute, the other is to splash over my head now and again. Thatís really helpful.

This is week has been great though. Extra hot and humid which means pop up storms by 5pm. Iíve been rained on each afternoon. I love summer rain durin* my commute, feels amazing.

I doubt any portable fan will do anything if you are moving over 3 mph. Water mist or wear one of those "cool band" headband things under your helmet. I do in anything above 70 and although not perfect, it does seem to help a little, if anything it at least reduces sweat in my eyes.

Potentially unpopular suggestion: as this is for a lower-speed commute in traffic, maybe exchange the helmet for a cycling cap? When I do big long ascents, where average speeds are 8-10mph, I strap my helmet under my saddle. I'm not super worried about tipping over, and if a car nails me from behind it's going to be at +50mph, where not having a helmet on would be the least of my concerns.

That, or figure out how to rig up a Parker Pumper.

I commuted daily in Southern Missouri in the Ozarks two Summers. The temperature was usually in the hight 90s or low 100s and humid when I was riding home. I used a neck cooler. Due to the humidity it didn't cool as well as it would in dryer air, but it worked okay for me. I hydrated it in a bowl in the refrigerator so it was nice and cold. I also drank plenty of water during the day to make sure I was properly hydrated. I can't see a fan doing much for me.

I used something like this. https://www.amazon.com/JellyBeadz-Br...k+cooler+wraps

How long is your commute?
Today my commute home in Phoenix was 113 degrees. I have about 8 miles and when it's that hot I take it easy riding around 13-14 most of the way. It takes about 40 minutes and really the only time I am truly uncomfortable is when stopped at lights for more than a couple seconds. On those stops I seek out shade, even if it means getting up on the sidewalk to find a tiny bit behind the light pole. I hydrate really well the whole day at work and drink a bunch on the ride. Also I will occasionally squirt water into my helmet if I do get hot. I wear roadie shorts and jersey because it really does cool better than mtb shorts or most other shirts I have, and color does matter. Try to wear as light of colors as you can.

That is what I do as well, if its hot and humid, I'll ride slow and ditch the helmet.

If its really awful, I'll skip the ride completely.

Try riding a different bike. Something that has thinner tires, is lighter, and easier to pedal...Heavy MTBs with big tires and a more upright riding position can be brutal and slow. I know because I have a SS MTB with big fat tires and often use it for commuting, on some days I just choose to ride FG which is lighter faster, more efficient and easier to pedal.

I wear a long sleeve under armour white heat gear shirt all the time now. At first it feels weird but that lasts for a minute. It wicks sweat and reflects the sun. Totally changed my hot weather riding.

Do you have the money for a new, better ventilated helmet?

Squirt your head with a water bottle. Right in the helmet.

Great idea! Just the excuse I need to get a new bike (Kilo TT).

@GrainBrain
Is that shirt that stick to your skin and show every contour of your upper body?
I might be too modest to wear skin tight shirts. I wonder if I get same cooling properties if I buy 'em larger than my size?

@RoadKill
It's only 6 miles. On Monday and Tues, I'm okay. On Wednesday, I'm getting sick and tire of commuting by bike. On Thursday, I'm really hating it. By Friday, I usually wake up and dread the bike ride and sleep in, then just drive the car. On the weekend I reenergize, and ready for bike commute again the next week.

I completely sympathize with that. I need the car Monday so my bike commute starts Tuesday. I really enjoy it Tuesday and Wednesday. On Thursday I just want it to be over with and if I ride Friday I pretty much hate it the whole way. Especially this time of year with the heat, it is very draining. Saturday I'm all ready for a mountain bike ride though! I think it's the repetitive nature of a commute, you can only switch it up so many ways.
I'll probably plan to just ride Tuesday and Thursday during the most intense heat, that will keep me enjoying it and still enough that my co-workers will look at me like I'm crazy.

The moisture wicking ability of those shirts tends to only work really well if they're tight against your skin. Nothing saying you can't wear a looser shirt on top.

What kind of condition are you in? Maybe if you got stronger and lost some weight, it wouldn't be as bad. I'm just guessing here, not accusing.

I've added a lightweight wicking skull cap to my normal attire. I first started using it on cooler morning rides only but find that it is helpful on hot days too. It wicks away the sweat so more of it evaporates than runs down my face, and the evaporation adds cooling. I can spray water on my head when stopped at a light, the cap absorbs some of it and then holds it as it evaporates, more cooling. As a side benefit my helmet pads last much longer.

I have chronic knee problem that prevents me from being in good fit shape. If I try interval training, my knee hurts. So, I just ride slow. And trying to eat less...but am addicted to unhealthy food like bread and pastas.

I've been changing my diet slowly over many years. I find I can't make drastic changes, but gradual changes work well for me, because I can stick with them. I find things that are healthful and I like, and I use them to replace crappy foods. I'm now at an ideal weight. Good luck with that and with your knee. Have you tried pushups and other things that don't involve your knee?

Interestingly enough, my average commuting times are shorter when it's really hot (same distance). I figure I ride faster to gain additional cooling, but admit that there is a fragile balance with such a strategy. It's a balance between production of metabolic heat production and evaporative cooling from the moving air. Evap cooling is less efficient for larger folks because of the ratio of body volume to surface area so weight control is important. Acclimation from conditioning is very important for anyone. I have a friend who solved his overheating issues with money - bought an e-bike.

I rode my 11mi commute home from work every day this week (Chandler to Tempe). Today it was 111F/107F heat index. I leave at 4pm which is about peak temp, but I ride hard to get it over with quicker. When it gets over 115F I soak my shirt first, but I don't this early in summer season so I acclimate quicker. It's gonna get hotter so I save my cooling tricks for when I need them.

I'd like to make a counterintuitive recommendation. I have these Columbia performance fishing gear shirts (uv rated) and a Buff neck protector thing that's UV rated as well. I know it sounds a bit strange but, I wear the neck gaiter and longsleeve Columbia shirts. And while it feels hot, it feel substantial hotter with no shirt or with a different shirt. I'm 5'9 250 pounds and I got my shirts in XL and they got me like a womans sundress. I wear that when I ride as well as for fishing. Rising they tend to flap a bit but they do make a big enough difference for me that I recommend them when I can. Keep in mind though, I'm only in new England which gets quite hot but that hot, at least not yet.

I too have been battling the committing bug but for different reasons. Lack of motivation sucks sometimes but I do enjoy myself out there more often than not.

best of luck

I regularly wear a sweat band to keep the sweat out of the eyes. It helps.

I have, on occasion, removed the helmet on days that I was pulling a heavy cargo load... at a whopping 3 MPH or so.

Especially, no helmet on places like the bike path, where there was nothing to hit.
