Endless Sphere

and I ended up going completely different way

Haibike Urban Plus. Due to a few difficulties with it as a floor model, I will pick it up tomorrow.

Thanks for the reply @scooterman101

Luna has their 4 year sale going on and I am ready to pull the trigger. On something. Crazy Lenny's has the HAIBIKE RACE S RX for $2200. The Luna option is a BBSHD with the 52V 6aH Mighty Mini for $899 and REI has the Cannondale Bad Boy 4 for $559 for a total of $1460. Now to make it a apples to app...

Curious how this goes.

Looking for a reliable CHEAP 20-25 mph set up for my Sirris Sport Disc.

Thanks for the lessons learned. Always helpful to us noobs

How to spec a controller would be a great sticky (if it exists I can’t find it)

How this going?

My Google-foo is weak on this one. I only found one reference to ZCRIDING on E.S. so I am making a post. https://www.aliexpress.com/store/product/50KM-H-20-28-48v-1000w-brushless-gearless-hub-motor-ebike-conversion-kit-1000w/1294587_32312457102.html?spm=2114.12010612.0.0.43ef2ffcyexC5Y Found this on...

Open source design... Sounds like Local Motors business model where everyone does all the work and they build it and make the profit.

Dear macribs:

In the "Input type" header the default is elevation, you can click on it and go to Google Maps. It will upload your elevation and distance profile after you close the window. Really cool.

Ride profile of going home with a simulation of the MAC 8T

Thoughts?

They do have a supermoto version. I don't see it listed on Luna though. That's what I thought. A neat "package" would be have a "upgrade box" to where you could buy one version, but it comes with an extra set of wheels and what not to make it a quick flip from street/urban to mountain bike. If this...

Get some street tires on that thing, a decent head light, and some pedals and you have a strong competitor for the motoped.

maybe I missed it but what controller are you using? Going from a 60V to a 40V pack seems like you would loose alot of speed.

At 250lbs I am thinking 15S4P but shallow charge them to 4.05 for a 60V 12.6 aH with the ability of a 120amp MAX rated discharge! NCR20700A cells from a Bosch/Dewalt packs.

its all about battery. I was looking at the NCR20700A that is found in the Bosch 18V 6.3 and Dewalt 20V 6.0 packs. I was going to run 3 packs series and 2 parallel as that would give me a 15s4p set up. The NCR20700B would be a better cell but you can pick up the Bosch/Dewalt packs for ~$50-~$60 Whi...

Maybe a Leaf 1500w motor is the solution...

6'5" 250lbs and the roads are decent with a few step hills as mentioned. I like where your at on the extreme performance. I would love to find a generation old down hill bike and go to town. Maybe next build. With the calculations I came up with I would have a peak available of 2400watts from the mo...

That is a nice unit but again, more money for less power, and putting the bus in the loop kills the time savings due to schedule.

Looks like the cyclone is the right choice. Especially if pedicabs are using them at a reduced rating.

My job pays my transit pass. So this has a negative cost savings. The reason behind it is to bring a little time back to myself. Being in the DC metro area my 8.9 Mile bus commute is 55-75 minutes. I can easily chop that down with our local bike trails. As far as costs power equals dollars and how f...

Anyone have any links to add?

Chalo: Thanks for the info. The 2000W is peak not nominal Nominal from what I can calculate is about 700w. I have one very nice 6% grade right off the bat that runs for about 1/2 mile. Then it tapers to a 3% grade for a little more than a 1/2 mile. That is 100 ft of the 300 ft of elevation rise over...

I like the 54V Bosch set up discussed earlier. I have read (please correct me if I am wrong) that a 12t MAC will give me what I want of a 25 mph with a 700c motor. I am not after a top speed bike. I want something that will hammer out mile after mile of stress-free riding. That is why I was looking ...

Hubmotors rule for commuters. The prime requirement for commuting is reliability, and I demand absolute reliability from my bikes, and a mid-drive can't do that.

What is your recommendation?

So after reviewing the new Bosche packs, I think that would be the way to go. I can get a 54V, 12.6ah for $315. (3s2p set up of the Bosch packs for an actual 15s4p overall) So being they are Sanyo 20700A they are rated at 30amps. So I can do a safe peak of 54V @ 120Amps for 6480 W of power! Holy cra...
