Depending on what you plan to haul, you might want a cargo trailer for your bike ... View attachment 24084
I don't think this is on the up and up. I'm not calling "troll" because there's no effort to start any drama. It just doesn't pass the sniff test for me.
I dunno. Something just seems a little off. I have no real objection. I'm just saying, is all.
- You ask newbie questions, and talk about your pedal bike experience, and then say you've owned 7 ebikes, but you don't say what they were or how you've used them or any information like that which would help us to answer your questions.
- You talk about braking power, but if you've had 7 ebikes, you know what the brakes will do.
- You ask how much you can carry, as though you've never carried anything before.
- You emphasize using the ebike as a car replacement and doing your shopping, but then you say that cargo is secondary.
- When someone answers a question, you've got a reply that sounds like you already know the answer, so why ask the question?
Carry on.
The idea I had was to use the bike and not maintain it. But it wasn't realistic and I've had to learn (or relearn) some of the maintenance basics. Truing a wheel isn't that difficult. Neither is indexing a derailleur. Hydraulic brakes can sometimes be little divas with their own mysteries. And then there are the electrics. I figure if the drive breaks and I'm convinced it's a mechanical issue, I will try to fix it. But if it's an electronic issue, there's probably not much I can do. It's proprietary stuff...
Amusingly an acquaintance tried my Haibike Trekking because she owns the same bike in the 25km/h version and wanted to see the difference with my 45km/h version. At the end of the ride she gets off and tells me that my derailleur is infinitely better adjusted than hers. So I indexed her bike the same way as mine and now she's super happy about it. Except that now everyone and his brother wants me to adjust their gears. Run for the hills...
BTW, I'm sure you'll be fine with the Bosch, not trying to scare you. But just remember the necessity for a plan B. That was really my point. Even with the best bikes, stuff goes wrong...
I test rode seven ebikes, never owned an ebike. I do own two pedal bikes that cost more than a very expensive eBike. So, I really care about bike technology, because I make a big investment in them. I consider myself to be a strong cyclist.
I have carried weight in my backpack. I am very conscious of weight distribution from 25mph accidents on my ordinary pedal bikes.
The objective stated in the title is to vet the idea of car replacement. I was hoping to have a sophisticated conversation with people at my own level of knowledge or experience.
In my opinion, a single ebike as a car replacement is a myth. I was skeptical whether an eBike could serve two purposes, because ordinary bikes are very much single purpose. eBikes seem to be the same as ordinary bike in this regard. A big consideration for me is the cost of a second battery. If I buy two eBikes, then the batteries must be the same. That was my main initial concern.
I think the best cargo solution for me is an ordinary pedal trike. Trikes are stable. I only have to pedal for a mile, that is very easy for me.
I am still uncertain whether the Trek Powerfly is the best solution. One reason is Bosch is supposed to release ABS brakes for eBikes this fall. I ride through several tunnels that are sometimes flooded or muddy. Fishtailing at the other end of the tunnel is scary. The tunnels go under major thorough fares and and Interstate 470. The tunnels are long and dark. In winter, water drips into the tunnels and forms giant ice cycles on the road surface. My mother lives on the other side of that bike path.
I coast down the hills in neighborhood at 30+ mph every day. I get tossed around quite a bit. Bike handling is something that I am keenly aware of.
Does this explanation put you at ease? Or do you still suspect something?
A trike provides additional stability from falling over to the side, at the cost of higher frontal drag. I have no trouble keeping the bike straight. It is just the front wheel whips sideways on obstructions, the tire grabs the pavement, and the decelerating bike throws me over the handlebar chin first. I've tried to buy a bike with addtional trail (caster) in the front fork as well as additional length between steering tube and bottom rail to clear the tire. No bike builder has any idea what I'm talking about, and none I've contacted builds his own front forks. All 26" front forks for sale on the internet have the same trail. I rode a 26"x2" bike in the sixties, my mother's 1945 Firestone, which was absolutely stable without hands through chugholes or whatever. No tendency to turn sideways. Bike was scrapped about 1980, way to heavy to ride anywhere but pancake flat Houston.Indianjo,
Would you now choose a trike for more stability, after your accident?
I think putting more than 15 pounds on a two wheeled bike unbalances the bike. For example, if I buy a twelve pack of beer and put it in my backpack, I feel like my stability is compromised more than I like.

Please Critique the 2019 Trek Powerfly 5 as a Practical Car Replacement Strategy
Finding a “commuter” bike with decent “cargo” capability might be an unreasonable tradeoff. Cargo and commuter bikes have different braking characteristics. Good braking requires low placement of weight. The top platform of a rear rack is too high to be the ideal location to carry weight. A rack container may also prevent you from making evasive maneuvers by moving your weight over the back wheel. I often reflexively get off my seat to shift my weight back backwards.
My car replacement adventure starts with a few steps into the foggy realm of eBike transportation. For the past two years, I rode my ordinary pedal bicycles three times the distance that I drove my car. I rode 100+ miles per week through the Denver winters. I naturally pedal between 20 to 25mph on the flats, so I prefer a pedal bike over a motorized bike, under normal conditions, loads and time constraints.
I sold my car, so the cost of a new eBike and a second battery is not an issue. I feel that only 20 to 40 days per year, e.g., 10%, are completely unrideable for me. I am willing to take a bus or taxi for the other days that are only manageable in one direction, e.g., (25%). The biggest impediments for me are midday heat, wind, daylight hours and wet surfaces.
https://www.trekbikes.com/us/en_US/...-hardtail/powerfly-5/p/23180/?colorCode=black
I reasons that favor buying the 2019 Trek Powerfly 5 are:
- The battery in enclosed in the frame, which offers some protection from the elements.
- The hardtail is the only option that allows for a full rack, which allows me to carry a second battery above the wheel.
- The 12mm rear axle allows a Burley trailer to be attached.
- The rims have a 40mm inner width, that allows for 2.4 inch tires
- The brakes can be upgraded to dual brake pads, for adequate stopping power with 300 pounds total weight, including cargo.
- The Nyon display allows me to manually configure battery power for different assist levels.
- The Nyon displays battery usage as a percent, to maximize battery life by never falling below a 40% charge.
- The kickstand supports up to 250 pounds of weight to load cargo onto the bike.
- I could adapt the Trek Bontrager Interchange base plate to support a cargo box on the rack.
- The rims are tubeless.
- Fender attachement bosses
The reasons why I might reject the 2019 Trek Powerfly 5 are:
- Walk mode is disabled by Trek, which makes the bike dangerous for crossing busy intersections when it weighs 100 pounds with cargo. This thought actually frightens me.
- The 100mm front fork travel may not be adequate for abrupt stops at 300 pounds.
- I might not find a cargo bike with a compatible 500wH Bosch Powerpack battery.
- The total weight limit for the bike is 300 pounds. I have not gotten an exact explanation for the weight limit, but I can only imagine the limit is related to stopping distance at 20mph for 300 pounds.
- At a lean 210 pounds, the 55 pound bike might be impractical for me, with a 300 pound weight limit.
- The maximum cargo capacity may be inconvenient for weekly perishable food shopping.
- Bosch has production ABS brakes for eBikes, which might be worth waiting a few months for.
- Evidently, the light wires cannot be internally integrated?
- No upgrade available for 15 tooth ring, apparently.
- Braking for heavy cargo necessitates the weight be distributed low over the rear wheel, rather than high over the rear rack.
Carrying 30 pounds of food per trip seems reasonable. The tubeless Powerfly tires are 2.4 inches wide. I imagine the tires make a stable contact patch to balance heavy weight because the tubeless tires are ridden at low air pressure levels.
Paying Walmart $10 to deliver food once or twice per month for bulky or heavy items is necessary without a cargo bike. Making two trips per week by bike is not a problem, because I can bike to Walmart in less than ten minutes on my ordinary pedal bike.
The entire 1.5 mile return route is a consistent 2% grade. I will brake the entire way back to keep the speed under 15 mph. I coast the entire route at about 15 to 20mph on my pedal bike. I am waiting to hear back from Trek about the most appropriate brakes. I would love to hear your suggestions.
I ordered the same brakes as on the highest specified mountain bike, the Powerfly 9.7. The Shimano MT520 4-piston Kolben hydraulic disc brakes would replace the stock Shimano MT200 hydraulic disc on the PowerFly 5. I believe the rotors are 203mm?
Since I do not know how to calculate stopping power, I decided to err on the conservative side. Perhaps, these brakes are overkill and will throw me over the handlebars? I reason that I need at least two brake pads for each caliper to keep the wear and heat to a minimum. 203mm rotors dissipate heat best. My Yeti ASR-C has Shimano Deore XT hydraulic brakes with 180mm rotors. I love the brakes.

I assume the front shocks will have enough travel for stopping with a 300 pound load? Waiting to hear back from Trek. I would love to read your feedback. Details:
- RockShox Judy Silver TK, Solo Air, rebound adjust,
- TurnKey hydraulic lockout, tapered steerer,
- G2 Geometry w/51mm offset, Boost110, 100mm travel
Some other items in the order that I appreciate feedback about are listed below:
- Nyon display to manually optimize battery power levels and battery life for different modes.
- A second battery for longer distance and redundancy in case of failure.
- Kickstand
- The same light as on the Super Commuter+ 8
- Integrated Supernova M99 Pure+ Headlight (1,000 Lumen, Light Sensor Mode Control),
- Integrated Supernova E3 3-LED Backlight
- The tubeless tire most similar to Schwalbe Super Moto-X, 27.5x2.4˝. Waiting to hear back from Trek.
I hope to fit 30 pounds of food into these rack containers, that seem quite small. I would love to hear what you think about the carrying capacity of these baskets and bag.

Another negative for trike or trailer, In my weekly commute I ride about 5 miles on a 55 mph highway on an 18" wide berm, with pavement defects narrowing the path down to 3" in some cases. The tractor trailers rarely give me any extra room, and absolutely never slow down for opposing traffic. A trike is absolutely too wide for that. The bodaboda sticks out only 10" from centerline. Also, the wind is picking up, which used to go dead from June 7 to Aug 31. Welcome global warming. I fought a 13 mph headwind last week, extending my 3.5 hour ride to 4.4. That is hard on the butt. The reason I'm trying to upgrade the bodaboda with a power wheel - to maintain 10 mph whatever the wind. Also to ride 40 miles in 4 hours to concerts in Madison or a party in Acme, IN. (country property is in NewMarket IN north Clark Cty, city house is in Jeffersonville 2 miles from I65 bridge across the Ohio).
BMS (battery management system) is internal in the battery for the 48 v 15 AH one I bought. There is a board under the shrink wrap that cuts out some stacks in final charge. Some batteries are infamous for having a computer in the battery, bionx is an infamous example (now bankrupt). I wouldn't expect one of those batteries to be compatible with any other system. I'm planning to mount the battery on the front rack, to weigh the front wheel down more and provide steady caster effect. I weighed the bodaboda loaded with two platform (human) scales last month, got 100 lb rear tire 26 lb front tire without me on the bike. That was without 6 liters on the front rack, which I usually have outbound. With the extra space in the frame behind the seat, my weight will bias to the front wheel and perhaps provide more effective caster effect on obstructions. 7 months down and OEM rear tire worn out , so far no problems with the front wheel whipping sideways. .
Edit after your last post. I require rim compatibility with 2.1" wide tire for my cargo bike. With 55 lb air that will carry 60 lb rear cargo with no hitting of rim on pavement. I ride the thick tread off road tires because they have longer interval without flats than city tires. City tire the bodaboda came with went flat after 7 months & ~ 1000 miles, thread was a little thin so I replaced it with a thick bump treac tire. Flats with 50 lb supplies on the bike are a P***. I do carry full set tools, two tubes, and an air pump. (one tube, made in *****, can blow up right out of the box, happend one time).
Hello BikeMike,
You have done a remarkable job of researching the Trek Powerfly 5. The best I've ever seen on any bike . There's little I can add, but I'll try.
I own and ride a Trek Powerfly 7 hardtail which is very similar to the 5. I ride my exclusively for enjoyment on hardpacked Rails to Trails and some roads, but no single track 'real mounting biking'...... I absolutely love my Powerfly 7 and would not trade it for anything. It's so much fun, it's solid, very stable and the Bosch CX Performance drive drain will climb a brick wall.
I swapped out the knobbies for Schwalbe Marthon Plus MTB 'Flatless'. I have had no problems. I really like them. I installed a Kinet Seatpost
and would not be without it https://cirruscycles.com. If I have any grips about my Powerfly 7 is the speed limitation of 20mph, but I knew that going in. I also have and ride a Trek XM700+ commuter, again which I love. That's my 'go fast' bike. It's a Class 3 28 mph. Combined I have 3200 miles on both bikes in the last year and I have had zero problems...none.
Lastly Trek service via my LBS is fantastic. I've told this story a bunch of times, but when my TreK Powerfly 7 arrived the handlebar controller
had been damaged in shipment. My LBS contacted Trek, the Controller was backordered. Rather then me have to wait around for the controller to arrive, Trek shipped another Powerfly 7 from Wisconsin to CT and I was riding in four days....Now who does that ? I hope this was helpful.
John from CT
Have you considered this EBike? Trek Police; If anything is going to have the load bearing and braking ability you want it is probably this one. It is based on the Powerfly.
https://www.trekbikes.com/us/en_US/...ountain-bikes/police/police-electric/p/22241/
If I was looking to replace a car I would get the Tern GSD.
The tern looks like a practical bike. Would you ride it regularly for 15-25 mile round trips, in hilly areas?
The specs on the bike look great!
I like the tires, but how are 20" wheels? I am used to 29" wheels. I am six feet tall, so the 29ers work well. I also have 650B wheels.
I don't know. Me personally, I tend to ride aggressively, but I only ride for fun (although when I did commute I rode with my hair on fire also).
That's why I brought it up; it seems like a nearly ideal, practical bike.
I have never owned a bike with 20" wheels. Obviously they are not going to roll as well as larger wheels. But the bike is not made for speed, so it may not be a big deal...unless you are used to always riding in "hammer mode." If you are that kind of rider, then the Powerfly (or some other sporty bike) would be a better choice.

Here are some get-me-out-of-trouble modifications and additions that I have made to my Powerfly 5 - together with my musings.
To keep me safe when I venture onto roads:
- Tyres: I've treated the Powerfly to a pair of Schwalbe Marathon Plus MTB (57-622) tyres with Slime-filled tubes. About ten days ago I punctured on my regular rail trail ride and, in attempting to remove the tubeless-ready Bontragers, learned the true meaning of "impossible". After a taxi ride back home and a settling cup of rooibos tea, it took more than twenty minutes to relieve the wheel of its accursed cling-fast rubber friend - this being accomplished with some serious assistance from a Park Tool PTS-1 Tire Seater and a pair of Lezyne Chromoly Saber Levers.
- Pump: Lezyne Digital Alloy Drive attached to the seat stay with Zefal DooDads.
- Tool Bottle: Zefal Z Box tool bottle (for tube & puncture kit) secured in an Arundel Sideloader bottle cage.
To keep the bike safe (especially at home in the shed):
- Rear Light: Cygolite Hot Shot Pro 150.
- Lock: AXA Block XXL frame ring lock and chain.
