Funny, it's not my bag, but I actually like it. Looks like it would be ridiculously comfortable to ride, and I like the power options that Juiced offers. Of course it probably won't be available in Canada.
We just passed $500K on the INDIEGOGO campaign. Latest update on the HyperScrambler with some performance test!
If you look at some of the newer videos where Tora is demonstrating the speed, he is pedaling to get the max velocity. Doesn't look like an afterthought.The Scrambler looks really fun, it's such a tempting price on Indiegogo! It seems like in almost all of the videos, the riders aren't pedaling and are primarily using the throttle - I imagine its because the seat is at a fixed height. It's like the pedals and gears are just for decoration. Thoughts?

My first thought was it looked like a moped from the 1970's. It'll sell, people in Europe buy these sort of scooters, I suspect city dwellers here will as well. Could be an inexpensive way to get around a city and unlike gas powered mopeds, you could bring this into the workplace or your apartment for security.
I do think the Indiegogo platform is a bit of a worry though. One doesn't pre-order or purchase from Indiegogo, you invest in the people making a product with the hope of a payoff in the form of a perk. No guarantees, no redress should anything go wrong or change from the original proposal. The instant you invest your money it's theirs, no matter how long it takes to get your perk, if you do get your perk. You can't even change your mind the next day, there are no refunds. Kickstarter at least allows you to pull out if you decide to before the campaign is fully funded. Credit card companies can't even do a chargeback because you aren't actually buying anything, you're investing in a product or a company. An Indiegogo campaign just adds to the many suspicions I've read here on the forum that JB doesn't have money to make anything until customers pay up first.
I invested in a Kickstarter ebike 3 years ago with several others here on the forum. Specs changed, frame changed, but the bid deal-breaker was an innovative battery pack that was the real selling point was scrapped due to the pack designer and patent holder pulled out of the project. We all bailed at that point because on Kickstarter that was allowed if the project wasn't fully funded. Indiegogo doesn't allow refunds at all, ever.
Nearly four years ago a friend, a well respected person in LEV's sent me some information on Tora. I was so impressed by Tora's knowledge and vision of LEV's. I thought one day I'd be buying a bike from what was then called Juiced Rider. JR made the best cargo bike on the market. Huge battery! Then the Cross Current came out and wow that was impressive. I was waiting (and still sort of am waiting) for a MTB. It just seemed like the natural next bike, but it has yet to arrive. Maybe it's the fact MTB are moving away from hub drives and JB is a hub drive brand. There's no reason it has to stay that way. I still think he could make a great MTB with a big battey pack at an affordable price.
Tora is a great designer, with vision and common sense when it comes offering battery packs people want. I've spent a few decades as a production manager for industrial products, nothing retail so I may be way off base, but the conclusion I come to from the many disappointed customers waiting for bikes is Juiced bikes needs a very good business manager. Tora is great at what he does, and what he does is give the people what they want, but timelines, deliveries, parts and communication are a mess. And now a 6 year old company starts an Indiegogo campaign to get money to keep the lights on in the shop. As far as I understood Indiegogo and Kickstarter were for startups.
I want to see JB succeed, but more models doesn't necessarily equate to more business and more money. There's been more than a few car companies fall into that trap. Good luck Tora and for the customers waiting. Here's hoping June is the month everything turns for the better.
Same here, Jazz. Kinda iffy at first; looks like hella fun now. Like @john peck says, now I just have to convince the wife...Congrats, I admit I wasn't a big fan of the Scrambler design when I first saw it. It has grown on me an looks to be a solid offering from Juiced.
Neal Saiki (Zero MC) is apparently a brilliant guy, but I haven't seen any new products or developments from him in years. No news or videos and I've looked. Micah has had good products. He has been here on the forum a few times. Maybe Tora will develope a serviceable pack. He's moving fast...Hi JR,
On that Kickstarter that we were involved with, I think that was the NTS battery system, named for the ‘inventor’. They pulled the plug on that and there was never much of an explanation. It was like “Sorry guys, that amazing piece of tech is gone and you’ll get the plain vanilla battery pack”.
The basic idea of the NTS pack was that the batteries were not spot welded together, it used some kind of compression system. Most things you load with batteries have a spring that maintains the contact as you put the cells in the case. Ebikes can draw 800 watts, and there are a lot of cells (50 is typical). Welding with thick strips means there is a broad contact area across each cell, and then they do multiple connections to other cells. Micah Toll has a good book on building ebike packs. He also distributes the Vruzend system.
If you look at the Juiced web pages, they offer a lot of information. You can see how the technical aspects of the industry have evolved. A couple of years ago, everyone was touting the high capacity cells, like the Panasonic GA’s at 3500 mAh. You don’t see much hype about high capacity, more than that GA for example, right now. One of the problems was capacity versus cycle life. Even the data sheets tended to show that the capacity would drop quickly on these high cap cells with maybe 100 cycles. So Juiced is talking about 1500 cycles. To get there, they are only using 80% of the capacity (charge to 80%, discharge to 20%). That’s the proven way to get the cycles.
The downside of 80% is that it turns your 3500 mAh cell into a 2800 mAh cell. Juiced is offering the 1 kWh pack for $500 on Indiegogo. So this is a great price, relative to what else is out there. But if you use the 80/20, it’s really a 600 wh pack. They are using the Satiator. If you DIY you can limit charge for much less, and with great precision. There are electronics boards from China to do anything with lith cells. I bought some 3s and 4s BMS boards for $3, what you need to build small packs. But you can get all this stuff in China, and they are obviously doing a lot of DIY and small scale engineering. Not much going on here.
It’s too bad DIY didn’t take off. The leader in DIY battery stuff right now is Jehu Garcia. But he is more of a power wall guy. You need hundreds of cells for that, only 50-100 for an ebike pack. But Garcia with his associate Tom (Ebay Alarmhookup) have offered a lot of used or otherwise remaindered cells and packs. I have 80 cells from hoverboard packs. The cells have been checked and rechecked by a lot of people. Anyway, if you can get cells for a dollar or two and you put 52 in a pack, it’s not a lot of money. You stop worrying about the cycles.
Getting back to compression packs. Vruzend seems to work, and they have had a couple of revisions. It is quite easy to check the connections on any pack with a thermal imaging camera. The hot spots are weak connections. The original Vruzend seemed to stress at 4 amps, the latest version is maybe triple that (they say). Jehu Garcia has a compression system, but it looks like the basic cell holders from China with a clean board. He had a video showing stress at 5 amps or so. Remember, you parallel cells in packs, or build voltage, so 5 amps is enough with 5 parallel sets. It’s 25 amps and at 50 volts that is 1200 watts.
All that power and a tiny battery.Check this out.
