Anyone know about the specs? All the site says is This article doesn’t settle it either: https://www.theverge.com/2021/3/4/22313508/porsche-electric-bike-ebike-sport-cross-specs-price From the article: Either way, it’s fun to see a Porsche product advertise a top speed of 25km/h. Can you...

This is fantastic! Saving a link that leads to their products: https://www.amazon.com/s?k=Grin+Technologies

How about 48V 20Ah Triangle Ebike Battery from UPP Factory for $389. With the "Leaf"-like kit you found for $399: (though reviews share I should have low expectation for shipping times)

As long as it's on Amazon, it's okay. It can be a full kit. Or a batteries-not-included kit, so long as there's a reasonable battery for the kit on Amazon. Or from all separate vendors. I don't recognize the vendors anymore and don't want to end up with garbage. I trust ES experience 1000%...

I have an opportunity to build an ebike for a school project, so long as all parts are purchased through a tight list of approved vendors (essentially limited to Amazon as far as ebike parts are concerned). I have a 26" donor schwinn, ~$1000 of budget for motor, controller, battery, and cycle...

Quick FYI, unfortunately I need to pause the build. A car accident (everyone ok) is reallocating resources away from the bike fund. To be continued...

Wow. The Edgerunner looks nice, but why o why is it twice as expensive as a Mundo? Perhaps that's why there's no used ones, anywhere.

Alan, I just read your BBSHD build article on Eric's site. Very impressive. And I also just got caught up with your post above. Thanks so much. You're making a very good case for the BBSHD. And I remember that Marin hill very well. I stayed up most of the night prepping 72V20Ah of Headways for...

To fit Dogman's suggestion of 3000wh, and Alan's recommendation of Luna Cycles and to use 18650 packs, here are a couple of options for battery power. 1) 4x 72V11Ah 18650 pack — $549ea (via Luna Cycle) — $2200 This gets me 3300wh, and at 72V, a lot more top end speed. 2) 4x 52V20Ah 18650 pack...

Thanks for your help dogman. I love the new 20" build! And the edgerunner looks fine, but I rode a $5k downhill bosch PAS middrive yesterday and while I was impressed with the technology, I was underwhelmed by the performance. If I haven't already been spoiled by ES and my very torquey, very...

Thanks for your feedback. I know it's a tall order. But building bikes with challenging goals is part of the fun for me. I plotted the route: https://www.plotaroute.com/route/243264. It goes clockwise around the lake, starting (and ending) at Zephyr Cove Resort on the Nevada side in South Lake.

Whoa! These Tangent Drives are awesome! This is the sort of tech improvements I was hoping to see since I've been missing from ES. Are you familiar with these? Will this make my power use more efficient since I can use the rear gears? How's the noise level? Is it loud due to chain and small...

Thanks Alan. You're right about the Tahoe loop feeling dangerous. I hope that going out ahead or behind the actual event will help keep me safer, roads being closed and all. Looks like I can get 52V80Ah with 4 of these 18650 packs (10lbs each) from Luna Cycle for $2500. 2 on each side of the...

Thanks Wes. Well that's an entirely different budget isn't it?! So you're saying you would do the Tahoe loop under 3hrs with 2.5Kwh Hobby King LiPo on a 48V 1000W eBay kit on a cheap bike? All for under $1k? I know I've been out of the game for a few years, but I have a hard time believing tech...

I'm not sure my budget is realistic. I've been trying to get up to date on battery tech. I imagine I'll need at least 60Ah (~3kwh at around 50V) to make the Tahoe loop and I'm having a hard time identifying the right balance of cost and density. For example, I could get 3 packs of 51.8V 20Ah...
