It might be helpful to check if you have any makerspaces near you, both for equipment and expertise.

Also curious about the motor choice. A hub motor is easier to mount and interface but since there are a lot of options I am wondering if this is because you already have a frame to build up from, or if there is something obvious I am missing. Does the motor option include the controller/wiring/display? (I have a bit of an industry background but I know very little about the electrical side of ebikes other than what basic diagnostics and what plugs into what because every major brand just has their own plug and play proprietary parts and batteries and all any customer cares about is power, legality and whether or not they have a throttle)

I already tested them once I finished that battery and as far as I could tell, after changing the controller settings to accept 60v, everything was working fine. Got the phase wires from hub motor connected and throttled and it spun. I just have to physically put everything together now and I should be set to ride. Battery controller and eventually dc-dc step down converter all live in the center cavity. I'm gonna add running, brake, and headlights, and front and rear turn signals at some point in the next month or so.

^Took this project to a huge cemetery and got it up to 32mph pretty easily which was extremely fun. still only have mechanical disc brakes until I can get a hydraulic disc bleed kit. It's -25 here with wind-chill right now though so I'm probably gonna be shelving this for the foreseeable future til it's warm enough to ride again.

Shifter cable busted at handlebar on my Tern HSD. I’m able to handle most maintenance including adjusting derailers but is changing the cable a DIY friendly fix or am I better taking it in. It’s probably time to have the computer firmware updated as well I’m just trying to avoid shop costs.

It’s pretty easy to replace cables, unless it exploded inside the shifter then it might be a pain to get the old one out

The inconvenience is the rubber spiral loom that gathers the cables together. If you're lazy, you could feed just the cable through. If not, it'll take a extra few minutes to pull the old housing and thread/wrap the replacement through. Iirc, the cables are entirely externally routed, though some of the wires go into the mid drive housing. It's all pretty intuitive, though.

Well, poo poo. After a few months of no use (stored inside) I charged my e-bike battery to full, and then the next day it showed half empty without any use. I assume I'm out $580 on that one?

Might just need a conditioning cycle. Check your manual, mine says to let it sit on the charger overnight (or ~12 hours), use it a bit the next day, then repeat two more times. If it's going to sit unused for extended periods in the future, store it around 50-70% charge and check on it every couple weeks or so to make sure it's not dropping to zero (putting it on to charge again for a bit if needed).

Yeah, nothing about that in the manual; it says specifically not to connect it to the charger for extended periods of time. It mentions that if it is less than 30% charge for an extended period, it can be damaged, but it didn't show that before I charged it.

If you are really lucky there's something wrong with your charger, and you didn't actually charge the pack like you thought you did.

I put new calipers on my cargo ebike, and it was worth every penny. I have a ton more confidence in riding around now that I can stop much more quickly. Also the squealing noise is gone!

I've seen a few sets locally purchased used to upgrade the mechanical discs that specifically come stock on value-priced cargo e-bikes. Nice that it's an option, nothing wrong with them. I find a third hand tool can help to really get these set up crisply if you like monkeying around with stuff.

I’ve read through the whole thread and now ready to ask if I’m on the right path here. I’m in the market for a commuter. I live in DC and try to ride year round. Right now I do it on a Craigslist special, 3-4 days a week. The commute is about 5 miles each way with minor hills, as a mix of bike lanes, trails, and in-traffic riding (some days I’ve opted for a bike share ebike at 10c/minute and loved the ride). I don’t think I want a step through, since I’ll have to carry the bike up/down a few steps every day (bike weight is not a concern). There’s a chance I’d eventually have to do a commute that’s closer to 10 miles each way, but I have no issue charging the battery in my office if need be. My budget started at $2,000 but after reading this thread I’m now eyeing the Gazelle Ultimate C380+ HMB which is on sale for $3,999. A LMB has it in stock as well. Am I thinking about this right? I’ll probably try to test ride it in a week or two.

Optimal carrying geometry/posture can vary a lot. For a middrive that's not too rear heavy, you might be able to grab it low down on the seat tube and keep your arm mostly straight.

I can't be the only guy who uses the throttle lightly to get the ebike up steps, right? I've never done more than one at a time, so I don't know if this works as an option for you.

That's a great price for the +. I think for that length commute it would be fine. Definitely test ride and make sure it feels good. I can't wait to get out on mine again for my commute once it becomes spring.

Fair point, I didn't consider how the weight balance changes by the battery/motor. It won't be a lot of steps so I wasn't planning on putting the top tube on my shoulder, just need two good spots to grab hold for a few seconds.

My cargo bike has a walk mode but it's kind of annoying to engage and I don't really find it very useful anyway. Maybe if I had to push it up a hill for some reason.

My cargo bike has a throttle, I use it all the time when walking the bike. An on/off switch would maybe be less useful but i'm lazy enough that I would probably use that if it was what I had. I'm either too lazy or not lazy enough to hook up the reverse function on the esc to an unused suitable switch I already have on the handlebars though. I guess I foresee a potential safety issue there so best not I think.

Hello! I've recently picked up a new bike, the Okai Ranger Eb50 and I'm in love! I have a Cty 2.1 from REI that I've used extensively but this new bike allows me to go three times the distance for the effort put in. Plus the integrated running lights and LCD controller are pretty cool too. Extremely pleased so far and my wife is looking for one after riding it once.

evil_bunnY posted:pretty sure neither your bike nor your assist system are off the shelf 😄  I took the box bike down on the lake for some tour skating today. The ice was surprisingly good even if the weather was gloomy and a bit windy (skating into a headwind kind of sucks.)  Front wheel motor with a lot of wheel spin leads to some funky spray patterns. This new fender could use an extension flap for rain (though it sprays mostly on the underside of the box so not really a big deal), but it would do nothing about the snow that sprays forward from the wheel before I run into it. I have to say though, if you're gonna have a drive wheel on a bike spinning in low friction conditions, front wheel spin is preferable to real wheel spin - much more directional stability that way.

I loving hate how the forward spray cakes the entire front end of my cargo bike too. I've got a flap for the bottom but nobody makes a 20" fender with enough front coverage.

I suppose modding a rear fender to sit up front should be doable. A full 180 degree coverage is probably a bad idea though - it's easy to bump into things with the front wheel when parking close to walls and so on. Ice speedway bikes have great coverage on their front fenders but I'm guessing it's not just to protect riders from spray but also other things
