diphthong

for me, the number is 6.

phone
bluetooth speaker
garmin
3 owleye usb charge lights for the caboose. one for the rear triangle and two for the seatpost.

i suppose i should be happy i ride older ultergra components so i don't hafta worry about
keeping electronic shifting going as well.

the lights are good for 7-8 hours on blink mode (which is how i use em) so they don't hafta be
charged after every ride. i still charge em anyway. gotten into the habit of charging the garmin
after every ride because there has been more than one time i thought it was at 80%+ charge
only to find it in the red at the onset of a ride. annoying.

how many things do you hafta charge up before setting out on a ride?

1 if you count my phone and I'm riding during the day, 2 if I'm riding at dusk/dawn with a headlight that I charge via USB cable. Everything else either is mechanical or has long lasting batteries I change once or twice a year.

You ride around with a speaker blaring music? That's pretty annoying unless you're on an empty trail.

I concur.

Bluetooth earbuds FTW.

Panza

iPhone 7
Garmin Edge 520
Bose Wireless Earphones
Front Light
Rear Light

Just replaced the battery in my powermeter. (Usually twice a year)

I'd hate to have to charge my shifters too. I've used them and they're nice, but I don't want an electric groupset. Every night my bike would be plugged to 7 wires against a wall...

Seattle Forrest

Depends. I have an Edge, but I don't mind riding without it these days, unless I'm doing a workout with a power target. Otherwise I use a Garmin GPS watch, and that's way easier to stay on top of the battery.

Lights this time of year. I wouldn't need them on weekends, but lately I'd rather ski on weekends.

EDIT: Forgot my power meter. Vector takes coin cell batteries, and mine need replacing soon. I think I have a pair on the shelf. Go through them pretty quickly.

I don't count my phone since I keep it charged whether I am riding or not. So for me, the answer is 0, except when I am touring. When I am, I carry several rechargeable AAA batteries and charger to power my camping headlamp and rear blinky. I read a lot after dark so I need to have spare batteries.

Hafta.

FeltF2Tarmac

Phone, iPod, heart rate monitor, Garmin, lights front and rear and on occasion the bike. So much for simplicity.

noodle soup

i listen to sports talk podcasts most of the time, so sound quality isn't that important.

get rid of the speaker and you're down to 5. Enjoy the outdoors, leave the music for the trainer

When commuting, I don't just have it blaring, but blaring full blast.

I find that when the speaker is blaring people don't shoot out in front of me, don't randomly change lanes into me, don't open car doors randomly without looking.

In fact, they ARE looking, they're looking for ME. And that's the whole damn point. Well that plus the fact that I have my hammer beats.

Tycho Brahe 

I definitely do! Compact bluetooth speaker in a top tube bag.

The whole point is for people to hear me. My weekday rides involve riding on closed roads (not trails, but actual roads), with many tourists walking cluelessly. They feel secure since they are not expecting cars, but forget about bikes. Sometimes there will be film productions. I make sure to blast something rocking (Slayer always works) when passing film crews.

I think using earbuds is dangerous and since I ride solo, gotta have some tunes.

To answer the question:
phone (charged no matter what)
bluetooth speaker (does not need to be charged before every ride)
smart watch (used mainly to control the speaker, also same comment as above)
lights for night rides. I rarely ride at night, but I make sure the lights are fully charged before going

Depends which bike I'm riding.

Dan333SP

Fair enough, whatever keeps people safe is fine in my book. I guess for the type of riding I do it wouldn't be necessary and would be annoying since I ride mostly rural roads frequented by other cyclists, so they'd have to listen to me coming and going and I don't think it'd make a bit of difference with the drivers.

RShantz

One - a Garmin.

rmfnla

I take my phone with me but turn it off when I ride...

DrIsotope

Phone (gets charged every night regardless of cycling)
Boombot PRO (generally charged 2x a week)
Front blinky (lasts 2-3 weeks per charge, depending on usage)
Garmin 520 (generally charged 2x a week)
Mio Velo HRM (again, 2x a week)
Stages PM (2032 coin cells, they last less than a month, I always have 2 spares in the saddlebag)
Cygolite Hotshot Pro (charged every Friday)

Add to this the stuff that needs charged on the wife's bike, and the kid's bikes, so I just built a pull-out that nestles under one of my workbenches with a 10-port USB charger in it. Oh, and I also have one of those Anker 3300mah USB quick chargers and two shorty cables that are always with the bike as well.

Nachoman

I pedal about every other day.
So Garmin, charged about once a week;
Front and rear lights, charged about twice a week;
Scosche heart rate monitor charged after every ride;
Di2, charged about once a quarter;
And I generally don't ride with my phone.

12strings

Same here...so zero...

I have a simple bike computer, but that battery lasts over a year, so I never think about it.

SpeshulEd 

I don't charge everything before each ride, but these are the battery operated things I use on a ride.

Phone
Bluetooth earbuds
etap/di2
garmin
heart rate monitor
power meter

Some bikes also have a speed sensor, cadence sensor, and lights if necessary.

I might also bring along a gopro and usb power stick if it's a ride I want to record.
