The last third of that route is down hill, so I've begun putting the controller in RECUP mode (regen braking) while going down steepish hills, and pedaling part of that distance to add regen and get more exercise. The regen is pretty minimal and it only adds 2% or so charge on a 10 minute downhill that would usually have me coasting at 20 mph or so.

The battery range is staying constant at about 45 miles with pedaling on flat ground at the lowest level of motor assist.
Thanks for the update; I was thinking of asking if you'd been cutting back due to rain or shorter days.

I've managed to fit in an hour of riding either before or after a rain shower, one good aspect of riding on paved trails versus dirt tracks.

I took a 20 mile ride to the beach along Newport's Upper Bay this morning, one of my favorite rides and a very scenic one, with a lot of wild bird sightings along the way.

By the way, I've learned a lot about managing lithium battery health from my LEAF experience and this forum. My bike's poorly written manual implies that I should fully charge the battery after each ride, suggesting that I should keep the battery fully charged for storage. I'm sure that the guys who wrote the manual were concerned about customers allowing the battery to sit at low SOC, with the potential of battery damage from low charge. Instead of keeping mine at full charge (displayed as about 98% SOC on the LCD "dashboard"), I try to keep it between 40% and 70%.

Lots of interest in the bike, by the way, at coffee stops, mostly from people in my age group, strangely enough. :lol: :lol:

I do the same thing Phil . . . . charge up, then ride to about 35% - 45% depleted, then stow it. I, unlike you, haven't been stout enough to brave the cooler days. But this morning it's in the 50's so whoo hoo! I'll be out & about in 20 minutes or so. I'll say one thing about riding my 1st "beach cruiser" style bike that feels strange. On the weekends, there are lots of bike riding clubs/groups that jet around Lake Forest / Irvine. When you pass a bunch of touring bike style riders on a grade (where Irvine Blvd crosses the great park) and their all wearing their jerseys ... padded riding shorts, toe clips etc - it just looks wrong to see a 'cruiser' guy blow by 'em wearing a Leaf T shirt and cargo shorts. :D

Now that we're 'officially' into summer, I was wondering if our e-bike riders are still using them.

Yes, absolutely.

I settled into an almost daily 10 mile, hilly ride on weekdays during the Spring. The ride takes me less than an hour, gets me into some beautiful local scenery, including some canyons and a reservoir, and a downhill with some outstanding views. Unless I have something else on the calendar on weekend mornings, I'll often take a 20 mile ride to the beach and back, over our excellent local bike trail system.

The run-up to summer has been busy for us, along with some changes in our child care schedule, so the morning rides sometimes get canceled in favor of some special time with our little granddaughter. But when time allows, you can bet I'll be out there.

From what I can tell, in 9 months and about 1400 miles of riding, the 10 AH Lithium pack on my Stromer hasn't seen any reduction in capacity. I gauge this by observing the SOC% on the LCD "dashboard" before and after my identical 10 mile rides. From what I can see, if I keep the level of assist the same (the lowest assist level out of four) these rides always take about 23% of the pack capacity, regardless of the SOC reading before the ride. So with a 10.4 mile trip length over the same route and back to base, I'm seeing the same percentage reduction in SOC. For this route and level of effort, I'm still estimating that the bike will go 45 miles.

It's also been fun to have the bike at some of our local LEAF group gatherings. Some of the folks are into biking, some have ebikes already, so they can compare mine with their own, and the test rides usually generate some grins from the riders.

Even as we discuss the fun of ebiking - I'm reminded of new york's take on electric assist bikes:
"... The officials in charge of New York City have had enough of e-bikes and are clamping down and intensifying enforcement on a law made back in 2004 that electric bikes are illegal in the entire state of New York. It was announced on April 12th on the city hall steps by city council member Jessica Lappin that the fine for riding an electric bike in New York has been increased from $500 to $1000. ..."

The rational is that many ride them in an unsafe manner. Funny thing - they don't ban autos, or regular bikes, or motorcycles, or mopeds for unsafe riding / driving.

The 'e-bikes' they've banned are in fact mopeds, capable of much higher speeds than the 16-18 mph max. typical of a pedal-assist bike. They do need to clarify the terminology.

I ride the E-bike with the best 'enjoyment to cost' ratio: the Currie EZIP Trailz. The 10AH OEM lead-acid pack was adequate for my needs because I want to pedal all the time, but for various reasons I replaced it with a 10lb (the OEM weighs 18lbs) Ping lithium pack with BMS. The bike has been unused for the last two weeks because I have developed several strain type injuries, but I'm eager to get back on it and ride 15 miles at a time again. Or, if I want, 50. ;-) I also avoid storing the pack at 100% charge, and with 20AH available I don't even need to recharge after every ride.

One thing to consider when looking to buy a bike, especially an expensive one, is what your priorities are. Hubmotors are discreet and quiet, but tend to be lacking in torque. Geared motors (the EZIPs use a parallel chain drive) are noisier, but also less complex and can give you whatever combination of power and speed you want, according to the final drive ratio. The big advantage with the EZIP is that you can buy one for $400, learn to ride under assist on it (it has both pedal assist and throttle), and if you like it you can upgrade the battery pack and/or change the drive ratio. If you don't like the bike, you've only spent $400, not $1400...

I don't have an electric bike, but I did see a man on a Segway waiting to cross Foothill Expressway at the light at Homestead today. That's a first for me. He was wearing a helmet. The area he came from is very hilly. He waved to me as I made my turn in front of him - EV to EV, I suppose.
