Me misinformed? Very likely. I did dig onto it and yes, it appears only the fork is carbon fibre and the rest is hydroformed aluminum. I stand corrected. But it also means the little chip my bike had in the paint was on an aluminum surface. So structurally no big deal.

That kind of price is out of the question for me. I am looking at the Aventon Pace 500 or the RadCity, which are $1500-1800. Seem adequate for my modest needs. I will admit that this commuter bike is the most expensive of the Trek e-bikes. I went in looking for a PowerFly, but they couldn’t get the large frame size until the end of Feb. But the commuter model had 3 in stock. Being so much more expensive would explain why.

The current bell of the ball. Trek Domaine something or other. Full carbon fiber frame, weighs 8-9 lbs less than the equivalent Giant road ebike. Cost 7k. That's a lot of money for nine lbs. The Giant road bike. Yamaha electrics, same battery size, Bosch electrics sound cooler than Yamaha, but having ridden both, I don't see any real difference. The Yamaha has three boost levels, the Bosch has four. I liked the middle boost level of the Yamaha better than the second or third level of the Bosch. As they say on the interwebs, your milage may vary. On both units I wish they had a bit more range. Mike

If feel better already. Something that can go 55 mph is bordering on a motorcycle.

I am typing this with my fingers because my toes are still frozen.
I just got in from a quick ride, 7 or 8 miles, in sub zero weather. Wasn’t bad, but not as much fun as I thought it’d be.

Now that’s dedication. Paul, you mis-spelled dementia. By the way, it will get to the mid 70s here today. I'm going for a ride later. Mime

Mike, The colder it gets, the less I like you!
You could could moderate my dislike by hosting a west coast jam for all us Soundhooligans in the winter.

Mike, The colder it gets, the less I like you! You could could moderate my dislike by hosting a west coast jam for all us Soundhooligans in the winter.David, I'd do that except there are some logistical problems. First off, we only have one spare bedroom. And the condo is in a gated community. Can you imagine Epaul showing up with the Maki bros.? I would hate to lose my standing at the swim up bar. I'm sure you know how clique-ish the blue hairs at the club can be. However, accommodations could be made, for certain members of the forum, who, for instance, lived in Beaverton. Certainly some palms would need to be greased, but it's not outside the realm of possibilities. Mike

An interesting thing about these pedal assist schemes is just how complex it is. This Trek bike has 2 or 3 microprocessors. One in the Bosch purion display, and one or two down in the motor casing (the dealer said there was two). A FW update to all three is done periodically by Bosch and you need to bring in the bike to get these updates.
When I think about what this technology is doing, it is not that far from a motion control application. I think this bike uses a torque sensor to decide when and how much assistance to provide. So basically a closed loop control system running in real time. So the quality of these bikes would be contingent on well the control system is implemented. I know Bosch is an expert in industrial motion control. So it seems like a natural extension of that expertise.

I know Bosch is an expert in industrial motion control. So it seems like a natural extension of that expertise. The Bosch system does measure torque, as well as pedal and wheel cadence or rpm’s, over 1000 times a second. The harder you work, the harder the motor works. I have the Class I Bosch system with only 250 watts and 20 mph top speed, vs your 350 watts and 28 mph. Your system may be different, but I find mine has a lag to it. Maybe it’s intentional to make sure the bike doesn’t get away from you. Still, starting from a standstill, it’d be nice if I only had to wait one millisecond before the motor kicked in.

I am checking garage sales for something I can peddle around the neighborhood. I may go as high as $100.

Put the mask on, then cruise residential streets for open garage doors. Sooner or later you’ll come across one with an eBike inside. Take the bike. Oh wait, your car... Screw it, with a nice eBike, you won’t need a car.

It pays to proofread but it is so far below minimum wage that it is hardly worth it. I may peddle the bike if I get a good offer but most likely I will pedal it to the florist shop for petals.

Screw it, with a nice eBike, you won’t need a car. Yeah, well eBikes are not even being considered. I will get a 5 or, if I am lucky, a 10 speed and will actually use pedal power to ride around the neighborhood for exercise. I won’t be going up or down mountains or riding from state to state but will just pedal around working up a sweat. Maybe the bike will have a bell and a light but that is as high tech as my accessories will go.

It’s just that on the latter you go faster, and although you sweated just as much, you were already blown dry before you got off the bike.
