last week's Blue Ridge Parkway trip

I have wanted to see the entire Blue Ridge Parkway since moving here in 1974. I had been up and down the northernmost 120 miles by car, and bicycle, but not the remaining 289 miles. Switching to the Bolt made the adventure even more attractive to me. I realized last week that it was now practical, t...

Re: Bacchetta Giro | BBSHD | 14s7p 35E | 500w PAS

Welcome to the best kept secret on the planet...electric assist high racers. Made for each other like peanut butter and jelly. I suspect, like me, you will soon be less thrilled riding a bicycle at over 30 mph for any length of time. Not surprisingly, low to mid 20's seems to be the sweet spot for e...

Re: My recumbent cargo bike

I went just the other way. My Linear had USS when I got it. It was OK, I just really prefer OSS. USS makes me think of lying on the hood of a car, hanging on to the windshield wipers for security.

Re: My recumbent cargo bike

Hey Warren -- nice travelogue! It looks like using more regen braking during your fog ride significantly improved your watt hours per mile. This matches nicely with my experience, but your 'sampling rate' of 100+ miles makes for better data. Nice top end speeds, btw -- that's the nice road hugging ...

Re: My recumbent cargo bike

This week, the Skyline Drive finally opened up, a month late due to horrible November ice storm damage. I decided, as my battery capacity has dropped from 53 Ah usable, three and a half years ago, to 42 Ah usable today, if I was going to do my dreamed of Skyline Drive trip, this was the year. Monday...

Re: My recumbent cargo bike

After a cold, rainy winter, spring finally arrived, and I started piling on the miles again. At 21K miles, one of the cartridge bearings in my 23 year old Aerospoke carbon front wheel seized up, and ate the hub bore and hollow aluminum axle. The company has gone out of business twice over the years,...

Re: 80% charge in one hour?

Would be impractical to meet them for things like ambulances, 18 wheelers, tow trucks, farm trucks, snowplows, school buses etc. In fact the effort would result in more, rather than less, fuel consumption. (Think about WalMart using 20 small hybrid trucks instead of 1 18 wheeler to get their goods....

Re: GM two new mid Drive Ebikes

It folds, and that leads me to believe it will be featured in a package with a Chevy Volt/Bolt/etc... Too late to be packaged with a Volt, as it is ceasing production on March 1st, 2019. They could package it with the Bolt, since most CCS fast chargers are blocks from the nearest restaurant/restroom.

Re: 80% charge in one hour?

The actual capacity of that 75kw battery will be greater by about 10% or even more. It is a sensible cushion for Tesla and not criticism by me. If I were to do the same, I would get the same result. Quite how the owner of the car in the video dragged his car to the charging point with a fully disch...

Re: 80% charge in one hour?

I ask this because here in Europe many governments, even down to the lowest parish council, are wanting to ban combustion engines in 10 or 20 years time and in the 10 years that I've been involved in this, the rate of technical progress (as measured in energy capacity) has been miserable. All good ...

Re: High performance & durability Cannondale Semi Recumbent

Ha. I have crashed recumbent bikes a lot, because racing. Usually you end up landing on your butt and sliding. This means you get road rash on your butt, upper thigh and usually your elbow / forearm. Not bad compared to the crash modes on upright bikes. What he said. I have only had two real bicycl...

Re: Chevy Bolt first drive

All the Bolt owners up north are bragging about driving in -10 to -30 F temperatures. We will probably never see that here. I charged the last 12% yesterday morning at 6:30 am, and then did a 20 minute precondition, which heated the battery, and cabin. I left the garage at 8:08 am, 36 F in garage, 1...

The bike is now more stable and less twitchy than my 700c roadbike - provided that you get it above 5mph. Easy to do with a short throttle blast. Yup. My two electric assist recumbents are more stable than any upright I have ever owned. I have ridden for many miles with hands pumping my knees, only...

This bike has a passel of potential problems and irritations bundled together with what seem like effective remedies for them.

I gotta say-- you've used recumbent layout, small wheels, and power assist astutely to apply their strengths to each other's weaknesses. I'm looking forward to see how this bike does for you in the long term.

Now I know where this cold snap came from. It is hell freezing over. :-)

I'm not sure why the difference between e-bikes and gas bikes in that regard, but it's there for sure. Gas bikes are the clear choice of the lost-yer-license crowd.
The difference is price...same reason most drive gas cars. The fuel savings sound good, but the upfront cost difference is huge.
