I’m now a few days into using an electric cargo bike (a Tern GSD) as my primary form of transportation. It’s…awesome.
I'll be dumping notes on the whole experience into this thread: joys, obstacles, tricks, rationales, questions, mistakes, details, discoveries…everything. Just a big old ongoing data dump. My hope is the notes here end up being useful to others.
Many posts to follow over time. If this is •not• useful to you, no worries! Mute the hashtag: #BikeDiary
Lots more to follow.
#BikeDiary A bit on the rationale:
Many reasons, but the big one is the climate. I have a venerable ~20yo stick shift Honda Civic. It won't last forever. When it stops running, what replaces it?
The Civic gets 25-35mpg. I drive it ~4000 mi/yr. Casual research & quick estimation suggests suggests that the sunk carbon cost of just •manufacturing• a car is approx the same as driving the old Civid for another •decade•. Replacing the Civic with •any• car — even an EV! — has a massive climate cost.
#BikeDiary It seems like the best thing I can do for the climate here is to keep driving my gas-powered Civic while working to make it so that when it finally dies, I'm barely using it and don't feel like I need to replace it.
In short: the goal of this cargo bike adventure is to move from a two-car family to a one-car family.
#BikeDiary One week in: I •love• it. It’s just…so cool. I'm hard pressed to think of the last time something introduced this much joy and life into my daily routine.
I got the model with the cushy seat in the back, and it transports my daughter quite comfortably. Her first several times riding on the back, she couldn't stop squealing with glee — and still does at least once per ride.
People do go on about their cargo bikes and their e-bikes. I totally get it now.
#BikeDiary My traditional bike is an aluminum frame cyclocross (a Redline, lovely bike), and it's nimble, quick, light, spritely. Riding feels like going for a run or skiing; if it’s a car, it’s some sporty little thing.
The Tern is none of that. People sometime say “minivan,” but that’s not quite right. It’s a station wagon. A really elegant station wagon.
#BikeDiary An unexpected effect of this bike being my primary transportation is the psychological experience. It’s mellow, sociable, relaxed. It kind of gets my brain on “cargo bike pace,” pleasantly energized and relaxed.
It rides like a bike, but with the electric assist, the energy expenditure is more like walking: I'll break a light sweat if it’s warm, but only a light one. After the ride, I feel pleasantly like I moved my body, but not like I did a workout.
#BikeDiary Why the mellowness vs my regular bike? Part of it is the electric motor. Part is the low speed: I settle in very comfortably at 16-18mph, but getting it over 20mph is damned hard without a hill.
A third surprising ingredient: the riding posture. It’s built to ride upright. I find myself instinctively sitting up tall instead of slouching (unusual for me!) or hunching over. Really different feel.
(Again, please mute the hashtag #BikeDiary if you don’t want to read all this!)
#BikeDiary The upright posture means I'm still •really• unsure about the handling: I corner overcautiously, go on and off sidewalks clumsily, etc. I just don’t have any instincts yet about where the limits are. At first I could barely start without wild wobbling. Carrying over experiences from my old bike, I keep feeling like I’m about to fall over, even though the small wheels and low center of gravity mean I’m nowhere •near• about to fall over. Lots of relearning happening.
#BikeDiary This is a good question from @charliepark. I got the S00.
Once I'd settled on the GSD, choosing this particular model was easy: (1) I live in MN, and want to ride as close to 12 months a year as I can manage. (2) My budget is “this is instead of a car.”
Put those two together, and it says “belt drive.” (The belt drive holds up much better in rain and snow, apparently.)
#BikeDiary That narrowed it down to the S00 and the R14, and as one person at the bike shop (Perennial Cycles ) put it about the R14’s extra fancy features, “If you’re not asking for it, you don’t need it!”
The Terns are super duper modular, which means that there are a •lot• of decisions to make (and also means that you will spend a •lot• more than the bare base price, be warned). I like the choices, but…be prepared.
May publish full build if there’s interest.
@charliepark
#BikeDiary Probably the bigger question for many is how I came to the Tern GSD in the first place. The answer is the obvious one: I asked around, got opinions from trusted people, thought hard about my needs, did a •lot• of homework, and then — this was crucial — I test rode half a dozen bikes.
I cannot recommend the test ride enough. No amount of photos, videos, specs, and explanation can substitute for experience.
After the test ride, the real contenders were the GSD and the Urban Arrow.
@inthehands one factor I’m thinking about for future bikes is the ability to move from a complete stop.
E-bikes are a big improvement over standard bikes (esp with throttle) but I still find it’s a little slow to get going, especially if I wasn’t downshifting several gears before stopping.
I’ve heard CVTs can be a great solution for that; was this a concern for you? And what were your experiences?
@harpaa01 @inthehands we have a plain Yuba Kombi to which we slapped an electric kit. The 0 to moving is snappy[1], the biggest challenge it to get used to the kids changing your balance in those critical moments.
[1] maybe too much. From my non motorized bike experience, I keep a foot on the raised pedal when stopped, and the system feels the weight as force and tries to start moving. Maybe I should talk to the BRM who installed it.
@mdione @harpaa01
I find myself adjusting the assist controls a fair bit as I ride. Pedestrians, narrow place? Assist 0/4 or 1/4. Needing to move through an area quickly, maybe get out of traffic, running late? 4/4 (“turbo”). Wanting to start quickly but not too quickly? 1/4 or 2/4 (“tour”) etc.
Maybe just because I’m used to a manual car transmission, this constant adjusting feels natural and even helpful.
@inthehands @harpaa01 same, except ours has 5 settings plus off. I usually ride on 2.
