Re: Heavy cargo and steep hills: Will my plan result in injury and carnage?

Thanks for all the great feedback! I don't think there's another place to come for advice on such a niche application. I'm currently thinking that the best bet might be a 32A Bikes at Work trailer with a utility box screwed onto it. There seem to be a variety of such boxes made for pickup trucks tha...

Re: Heavy cargo and steep hills: Will my plan result in injury and carnage?

Why do you need a longtail if you're carrying the cargo on the trailer? Is it that a standard wheelbase bike would be more likely to tip instead of turning the trailer? Are there any lockboxes / utility boxes that are a natural fit for a Surly Ted or a Bikes at Work 32" and only require some basic d...

Re: Heavy cargo and steep hills: Will my plan result in injury and carnage?

Thanks for the feedback! Is there a trailer that can carry ~300 lbs and features a locking box or an aftermarket one that can be installed without a lot of custom modifications? The Bikes at Work 32" looks like it would fit the bill, but I don't know about the box part.

Re: JUMP Bikes Bike share — Electrified.

Good video summary! I believe there is a place for docked and dockless, electric and pedal bike share, and shared scooters and NEVs (neighborhood electric vehicles). The advantage of docked share is predictability: You can be reasonably assured that there will be a bike waiting for you at each stati...

Re: JUMP Bikes Bike share — Electrified.

From the photos I saw of the SF operation they have guys who run around in what looked like regular extended vans moving the bikes around, must be some manpower hours involved and resulting expense. Too bad they don't have personnel on ebikes with trailers full of batteries doing the swaps. Totally...

Re: JUMP Bikes Bike share — Electrified.

I’ve had a few bikes that were badly skipping after only 2 weeks live, which tells me that Nexus hubs are probably a bad idea on shared bikes that people are going to beat on and shift under heavy load. I would guess that Nuvinci hubs would probably fare better. arthurtuxedo: Interesting report ther...

Re: JUMP Bikes Bike share — Electrified.

I've taken a few rides since they went live on Thursday. They are front hub setups with Bafang motors (couldn't tell which one from the label). Power is pretty decent, and not far off from my eZee 250 RPM @ 36V, 20A (basically a MAC 12T). Shifting mechanism is a Nexus 8-speed hub. There is no thrott...

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

My 2 main concerns are that 1) I want the full 30 amps @ 36v when I venture into extremely hilly neighborhoods or pull a heavy load or passenger and 2) the converter doesn’t look like it’s remotely waterproof so I’d like to disconnect it on rainy days. Sounds like my best bet is just to hook it up u...

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

Can this be installed in a way that it can be switched on / off or bypassed easily? I have a 250 RPM eZee motor, and love the torque but not the ~21 MPH top speed. I am getting ready to install a 6-FET Lyen controller that can handle 36V @ 30A or up to 72V @ 20A. I'd like to run the battery's natura...

Recommendation for vertical bike hooks?

I am looking to hang 2-3 bikes vertically on a section of wall about 40" wide. There are some products and reviews out there, but they don't give much guidance as to whether they would support the weight of an Ebike. Has anyone had luck with certain products? My current bike weighs about 60 lbs.

Re: Bamboo / BBS02 / Nexus IGH

I am very interested in the bamboo frame concept, as I have an idea for a bike that does not currently exist and I would not want to have to learn to weld and buy a bunch of metalworking equipment plus rent the space. How did you account for the diameter shrink of the tubes? Wouldn't that cause them...

Re: Reconnecting some wires, a beginner's journey

After a very helpful e-mail exchange with Lyen, I got the motor working again by twisting the ignition wires together! I guess the only thing the ignition key did was complete a circuit, so now I can take my time watching tutorials and still have E-power in the mean time. The power in this thing rea...

Re: Reconnecting some wires, a beginner's journey

Turns out the wires in the second pic are just to the ignition key, not connecting the battery and controller like I thought. Received my 60W soldering iron and 60/40 core today so I'll make the attempt soon. I can't see any way to route the wires properly through the bottom of the frame without cut...

Re: Reconnecting some wires, a beginner's journey

I received a couple hundred bucks earlier than expected, so I'm thinking that I'll go ahead and order a Cycle Analyst v3 if I'm going to be messing with the wiring anyways. Will the c2013 eZee controller have a plug for it or will I need to do the shunt mod? I also have my eye on the TDCM torque sen...

Reconnecting some wires, a beginner's journey

Hi all, I finally got the project bike that I posted about a few months ago into rideable shape. It rides like a dream, I love the gear hub, and the hydraulic disc brakes I installed the front allow braking distances that could probably beat most cars. However, all the part swapping and jostling has...

Re: What will it take to make ebikes, More mainstream ?

You have to also account for how many vehicles are on the roads and how many cyclists on riding. Another way of doing it is, for the total distance of ALL users in one year, much harder to find out. I agree with the sentiment, but total miles would be highly misleading in favor of making cars seem ...

To answer the question that Izits has been asking, which is why wouldn't people choose the option that results in the most comfort and convenience, there's a lot more to it than that.
