Some more points of comparison that come to mind, these available in the States: Gazelle Ultimate C380 HMB: Same belt and hub, but without automatic shifting, $4000. Add $500 for Class 3. Gazelle has a broad U.S. dealer network. Watt Wagons Atom: If you build it out with the Archon X2 1000W...

In Europe, the Veloretti e-bikes come to mind. The motor is from Bafang, and European regulations limit it to a lower speed, but otherwise it's the closest bike I've seen to Serial 1, and at nearly half the price. You can quibble with details, but then consider the price. I think Serial 1 bikes...

If you watch this video about the downsides of shaft drives you may find your enthusiasm for this bike to be tempered.

The Garmin Edge 530 is currently on sale for $250 (as of today, I think). I just bought one.

@dougpnirv sorry for the delay. I have the SC-E8000 controller. I always toggle it to display RPMs at the beginning of my ride, and it stays on RPMs for the entire ride. I'm not sure if the other controllers operate the same way or if they revert to speed. I wouldn't make much sense to switch back.

I'm late to this thread, but I've been shopping for a first e-bike for my wife. This bike looks fabulous for the price. What comes out to me is the quality offered here: Deore groupset 4-piston brakes in front decent suspension fork decent rims (don't know the details but sounds like attention...

+1. I can pick some nits with my BMC, but its 20 mph cutoff is not one of them. When I'm tallying up pros and cons looking for a bike for my wife, class-3 is a very mild "con" because I'd be paying for something she won't need. That said, many of the nice bikes out there are class-3 anyway. In...

I've never ridden a hub-drive before, but how does that change the issue of cadence? Given two bikes with the same gearing, one a mid-drive and one a hub-drive, both bikes require the same minimum (top-gear) cadence for the same speed, no?

The above chart is for my bike which is not a Priority Current. With that chart, the gear-inch numbers for my bike (post #97), and the gear-inch numbers for the Priority Current (see post #93), we can estimate RPM needed for a given speed in the Priority Current Shimano gear #5.

I see. For my bike, bikecalc.com/speed_at_cadence gives me the table below. This suggests you'd need to pedal in the upper 90s to reach 28 mph on the Shimano Current, and close to 90 RPM on the Enviolo Current. This tends to the athletic side, but is not excessive. I usually aim for 90 RPM. Keep...

According to this calculator my e-bike (BMC Alpenchallenge AMP Cross LTD) has this gearing in gear-inches: 1 30.4 2 34.82 3 39.25 4 45.05 5 50.58 6 58.04 7 64.12 8 71.58 9 80.98 10 93.42 11 110.55 The Enviolo Current is geared a bit lower but otherwise similar. The...

Thanks! Where did you find that chart?

The Shimano service manual specifies this as 177mm.

How many teeth in the chainring and cassette on the Priority Current? And how wide are the tires? I'd like to compare the Current's gearing to known bikes, but I don't see Priority listing these specs.

Who makes e-bikes with the Rolhoff hub, available in the US? So far I can find: Riese and Muller Wattwagons Optibike Zen (upcoming) Is that it?

By the way, if you are considering using stunlocker.com to derestrict the motor, be careful with your firmware revision. I think stunlocker does not work past 3.8 because starting with 3.9 Shimano shut down some access. Check for yourself to be sure. When I received my bike a month ago it was on...

I have walk mode on my E8000 bike. I have not used it yet beyond testing it. Regarding the switch units, Shimano makes several variations. Below I show the left side—the side that controls the assist level—but there is an equivalent right side. Different bikes come with different controls, but...

Agreed. Also, I should have given the caveat that I am notoriously and irritatingly noise-sensitive. Noises that other people don't hear often bother me a lot. I may be getting an e-bike for my wife soon, and I'm eager to compare the noise level of whatever she ends up getting. I agree that the...

I recently acquired my first bike, which is equipped with an E8000. You can read about my impressions of the bike as a whole in this thread, but here I'll respond a little bit about the E8000 specifically. Since I've never ridden any other e-bike, and since I haven't had this bike for long, take...

Franco, how much do you pedal unassisted in these rides? Do you turn the motor on and off often or do you mainly leave it in Eco? I am an inexperienced cyclist with poor skills, but I am enjoying a similar BMC AMP with flat bars (Cross LTD). Today I did a 50 km ride with 1000 m of climbs, which...
