Hi all. I have looked around, and the comments and suggestions about choosing a bike that I have seen seem to be unusually thoughtful and helpful. Those who donate their time are doing a real service.
I am 53 years old, reasonably fit and weigh around 170 pounds. Maybe a few more than I would like, but neither overweight nor limited. I live in Seattle where I am an attorney. I have been looking for a nice office near me, the market is tight, so I am expanding my search. Monthly parking in Seattle costs $300, and even if I could afford it, I don't want to. I live in a part of Seattle called West Seattle, and I am considering office space about 7 miles away. When I leave my house, I immediately go up a hill that is about a mile long and a 300 foot climb. It then immediately descends about the same 300 feet in the same mile distance. Beyond that, my commute would be dead flat.
The City of Seattle is now run by a bunch of lunatics who, among other things, have a bike fetish. They have been installing bike lanes even in places that have not seen a bicycle in years. The City passed a huge levy for bike lanes. We were told that they would cost about $865,000 per mile, and a big report came out a month ago that the actual cost has been $12 million per mile. Mistakes happen, right? The point is that I live in a city that is at least nominally very bicycle friendly.
Personally, I think that the solution is a Lightning LS 218 motorcycle so that I could get anywhere yesterday, but my wife and two sons think that my lengthy history of mishaps like a 30 foot fall into a a ravine while hiking alone off trail somehow disqualifies me. My wonderful mother was an ER nurse in her younger days and seems to have created a long list of false memories of treating motorcyclists whose brains and bodies were splattered here and there. She says I cannot come home to visit if I have a motorcycle.
So maybe the answer is an electric bicycle that goes 90 miles per hour. OK, that last part was a joke. But my commute would be on fairly safe and normal roads. I can take the low bridge, and the speed limit will never exceed 30 mph. I can park a bike and even an electric bike for free, and I might end up finding it useful for broader purposes.
I am a researcher by nature and profession. I have more spreadsheets with more information that I do not understand than you would believe. I have not yet test driven an electric bike for the same reason that I would not test drive a car until I was ready to buy. Since I have never ridden any electric bike, every test drive is going to be amazing. I am going to have no ability to make meaningful distinctions.
In looking at bikes so far, I have realized a few of my preferences. Faster is better than slower. Up to a point. Movement on electricity alone is better than having to pedal. The Delfast Prime claims a range of 236 miles, a top speed of 34 miles per hour and costs $5,000. Those are impressive statistics if true, and if I were inclined to send $5,000 to the Ukraine on a whim, I might think about it. But it is not a bicycle. It is a wannabe little motorcycle, which gets me kicked out of my house with no way back to mom.
So I am thinking that an electric bike should look and as much as possible feel like a bicycle.
28 miles per hour sounds a lot better than 20. A lot better. Assuming a 7 mile commute and top speeds, 28 mph would get me to the office in 15 minutes, and 20 mph in 21 minutes, or a difference of 6 minutes. Time is precious, and I even bill in 6 minute increments, but the day I get bent out of shape over a 6 minute difference in a commute is the day I should try walking for comparison purposes.
Aesthetically, I much prefer straight lines. No matter where you put the battery, I just do not like it. Bosch now has its PowerTube 500, and I suspect that other companies have or soon will have similar products. That strikes me as an elegant solution. Making this a requirement would limit the number of candidates, but it seems that it would limit them to high quality, up to date models.
The motor is something that I do not understand at all. Bosch seems to be the Microsoft of electric bikes, but others swear by Brose or companies I have never heard of. On top of that, I tend to generally follow technology advancements, and the last month of two has me wondering if I might be setting myself up for regrets. First, a British engineer named Ian Foley, who has a deep Formula One racing background, allegedly has found a way to economically manufacture motors with spoke magnets. It is a known idea, but making them cheaply is new. This whole area is new to me, so I may be missing the boat, but the focus seems to be one the watts per kilogram. the Bosch Performance Line 28 mph mode weighs 4 kg with 350 watts. So that would be .0875 kw/kg. Foley's company Equipmake claims that they can produce 9 kw/kg. I must be missing something because that would be 102,000 times more than than the Bosch. But it must be quite a bit more because the article said the Siemens made a world record prototype in 2015 that reached 5 kw/kg. It looks like major advancements might be on the horizon. The Equipmake is not entirely vaporware because it is being used in a new Ariel Hippercar that claims 1,180 hp and significant range. Before the smoke had even cleared on that one, A Belgian startup called Magnax claimed that it has developed a compact axial flux electric motor and says it produces sustained 7.5 kg/kg with a peak of 15. Again, I am way out of my league here. My information largely comes from newatlas.com, supplemented by the companies themselves. No one wants to be the Schmuck who bought the last electric bike before they started flying.
All that said, Bosch and Brose, probably in that order, seem like solid, safe bets.
When it comes to the rest of the normal bike parts, I am hopelessly clueless. Some of the posts here have emphasized how important that is, but I do not know where to begin.
So with all this in mind, my woefully inadequate thought process looks like this
