Gorgeous! Which volcanos are those?
Show us pictures of where you ride your ebikes!

Today was a little warmer (25-27C) so I thought I'd try to stay close to water. The easy choice was down to River Road, heading West to Deas Island Park.
What I did not count on was a stiff headwind the whole way there. I had decided that I wanted to go for low assist levels/higher battery efficiency as opposed to the previous "fastest 40", but still try to keep the km/hr up.
Have been keeping an eye on the smoke forecast and figured today was going to be it for a while. https://firesmoke.ca/forecasts/current/
You can see it's just starting to hint of haze/smoke coming, looking to the NW...
End of the road into Deas Island Park...
This area is used a lot for water ski/rowing/kayak etc...
Heading out of the park, saw a cool car...
I don't think I've ever averaged 2km/battery percentage...
Heading back along a service road right beside Hwy 99. Super safe, but piles of traffic/noise...
This guy can't decide whether he likes chain drive or belt drive...
A spot of solace/shade and some water at... um... Watershed Park on the way home...
Almost 40, but not quite. Would not have beaten the previous anyway, but mission accomplished regarding higher km/battery consumption...

On the pictures they are hard to see but in person they are much more impressive. Road to sherrard point will be closed for repaving for the rest of the season on Wednesday so I took a ride up. Over 3000 feet elevation gain in 14 miles. I was going to ride a regular bike but it's hot and I wanted to enjoy the ride.

So can you say or guess what kind of wind speed you were fighting? And what effect on the battery it had? Curious minds ...Today was a little warmer (25-27C) so I thought I'd try to stay close to water. The easy choice was down to River Road, heading West to Deas Island Park.

Excellent question. I wish I had recorded it at the time.
All I know is that when I hit the flats next to the river the wind was in my face immediately. Current conditions (4 hours later) are around 12km/hr with gusts up to 25km/hr. I'd say at the point of my ride it felt like 15km/hr with gusts to 25 or more?
Normally I would have kicked up the assist a notch, but in this case I left the assist at 2 (out of 5) and just pushed.
I suspect I may have exceeded 2km/battery percentage instead of coming home slightly behind that (1.87).
Just an unscientific guess...

At least it's a start. I have a suspicion that a nonstop wind will eat a battery even faster than a hard climb of similar effort, based on the few times I've been out in real winds. Usually when it's windy, it's also rainy here, so I'm heading for cover...

You can get a feel for the relative resistances involved at any given ground speed by looking at the 4 common scenarios explored in my wildly popular crossover speed post.
All 4 scenarios are for a relatively upright 200 lb rider in street clothes on a 65 lb commuter/hybrid bike with corresponding tires on smooth, hard pavement at ground speeds up to 28 mph:
A. No wind, 0% grade
B. No wind, 5% grade
C. 10 mph headwind, 0% grade
D. 10 mph headwind, 5% grade
Moving against absolute (not relative) total resistance is what eats up batteries. Turns out, total resistance is greater in Scenario B than in C at all ground speeds.
So, doesn't take a steep grade for gravity to out-resist the air in a 10 mph headwind. But as headwind speed increases, that story will change.

Here's a calculator from Bosch...

That looks refreshing. Bloody Caesars seem to be a popular libation up here though I can’t say for sure if they serve this version in your neck of the woods. I s’pose the blend of clam nectar and tomato juice might be an acquired taste for some.

No, I haven’t run across that version here! Sounds interesting!

I think that it might unofficially be Canada’s national drink. A celery salt rimmed glass is garnished with a stalk of celery and lime wedge. Vodka, a dash of tobacco sauce and Clamato juice create a distinct piquant flavor that is familiar here from coast to coast.
I’ve even used my dry rub recipe to rim the glass which gives it more of a kick.

Getting our first whiff of smoke from wildfires, but it does make for pretty sunsets.
Spent an hour poking around the Everett waterfront waiting for my kid's practice to wrap up last night.

A lot of open spots on the public docks

It was another glorious morning for a ride in the countryside. The canola fields are nearing their peak flowering stage and the blooms should continue to be visible for another 2-3 weeks.
