Anyone know what the shipping cost to the U.S. is going to be ? So far with just a couple of options, early buyers will pay $ 704 ( $ 668+Pas Sensor + Brake Cut off Switches ) , before shipping costs, so close to $ 800 ! and if they do raise the price by $ 100 at some time, that would be around $ 90...

It certainly is deserving of the name Pro . It is the most professional looking , mass market style of drive . ( Tangent and Lighting Rod's have that beautiful custom look though ) Every thing about it looks to be quality , except for ... only a thumb throttle for a throttle option. Thumb Throttles ...

He says he is only going to use/install one cog on the rear wheel. A mid drive would be better , but only if he ran many cogs on the rear with a derailleur. For what he wants to do , if he were to use a mid-drive I would go with one of the newer systems that uses 11-48 or 11-50 tooth cog set. 8/9/11...

The New Mac, ( available for almost 2 years now ) it has a temp sensor inside it. The first generation Mac , that I have did not have a temp sensor inside the motor. When bought from a place like em3ev.com you can get the necessary items to make the temp sensor work correctly. You will need a 12 t M...

Back to looking at this again, since some DIY RC mid-drive builders here are stuck on low power / just assist levels of power . ( It is entirely possible to have higher power levels by using a freewheeling crankset for short bursts of high power, not pedaling, ... then use the lower power levels for...

When it comes to safety I do not kid my self , for instance ... This last Sunday I decided to take my e-bike on a country road that connects to a mountain pass that I was then going to go up. I strapped on my 14s battery packs for faster speeds , however Just 1 mile into the ride on that road there ...

Not Possible ??
or
Just not desirable for you because of your Son and Girlfriend .

Parajared, You have the talent, and the tools and shop space to make your own trike Wider , Longer , Full Suspension. Using tubing you can buy at any metal supply warehouse . Like 3x3 inch or 2.5x2.5 or even rectangular tubing for a little more strength in one direction. Using 26 inch wheels front a...

I must use a throttle, Can you make a switch to put on the handlebar , so that you can have both the temperature sensor, and , the throttle connected to the controller then switch back between each ? Note that most everyone who does DIY e-bike conversion on their bike would know when they are pushin...

The safest speeds for a E-Bike are dependent on the Frame and Components used, All you have to do is look at the latest 8 or so years of Down Hill Bike Design and the brakes they use. It is that easy. So you can go the speeds ( legal speeds ) that a Motorcycle can go, as long as you have a strong Fr...

Interested as well, If I got this little ( low power mid-drive ) I would pushing the limits of it's Volt and Amp usage, so does this Lingbei motor have a thermal shut down feature for when it starts to get to hot ? Now it seems this motor has possibilities (enhancenments in future firmwares, either ...

Funny, Have you seen a jackshaft ? A jackshaft can be put in the main triangle of the frame, location dependent on the style of full suspension design. A jackshaft will allow a very large amount of different gearing options. On the jackshaft two chainrings. to the motor a large road chainring , to t...

Kepler, Instead of using sandpaper on the motor , what about making a sleeve out of Delrin that has hashtag marks around it. That should be softer on the tire . The Derin could be machined out of a solid block, wonder what that size block of Delrin would cost ? , or be printed thin enough that it co...

Not until a couple of posts above did I find out you have designed this drive for low power, I ( and I am sure others ) am still interested in what you have done here for its simplicity . The high power RC drives up to this point in time use expensive custom machined parts for the reduction , those ...

FZBob, With your last post I see you have designed your RC mid-drive for much lower power settings than I have ever seen a RC design listed here on E.S. , do before. With such low power assist I can now see why you have now discarded the freewheel. I am looking at RC mid-drives, or perhaps a frictio...

With a heavy 1,000 watt direct drive rear hub motor,
you are better off by just buying a frame that is designed for such a heavy hub.

Vector Frames
EEB Frame
Futur Frame
ION 2.0 Frame

You can find examples of these frames at the ... Items for Sale - New , section here on Endless-Sphere.

People , buy these frames,

so that Artur can start selling frames ( light frame ) with a better swingarm, and with the main frame that has the opening on the side ( not bottom ) for the batteries , so that we can take out the battery pack each ride .

FZBob, I like very much what you have developed here, as much as I like the simplicity of a Friction Drive, I want to change out tires for the different rides I want to do, meaning street tires, then aggressive mountain tires for riding in the loose dirt riding conditions where I live, most MTB ride...

John, Isn't that taken care of by buying a crankset with a freewheel ? not ever having ridden or even seen a bike with a freewheeling crankset it really is a question for me. Since I ride for my primary way of transportation, ( no operating car at this time ) I often ride without peddling . So I nee...

I think the Specialized uses a Brose motor. By the Way, there is a difference ( improvement ) with the newer model Specialized Levo's, I have been watching the video reviews, and there seems to be now 3 or more versions/new models over the last couple of years. The latest one , 2019 model now on sal...

Andre did this on his 2013 Specialized Secteur Expert , on page 14 , about 20% down the page look closely at the picture of the BB, notice how he made a great looking thin clamp that bolts around the BB shell of the bike. That the plate is then bolted onto with three bolts/allen machine screws. not ...

No that is not the freewheeling crankset I was think of, however that is a good find, I like that there is an option to the Square Taper, and I SIS type of BB/Cranksets. At that price of $ 432 I would just buy a freewheeling crankset from a vendor, here are a few parts to make your own from SBParts ...

Kepler, I also think that when using a RC motor on a Full Suspension Bike for a mid-drive that drives the crankset and thereby also drives the rear cogs on the cassette , that the motor and reduction stage , should be located up in the front triangle of the bike above and a little forward of the cra...

Kepler where can we buy this mini Vesc ? Cost with shipping ? Also i have a new mini Vesc to test. This Vesc is half the size of the standard 4.2 Vesc with exactly the same power rating and features. It also has a built in heatsink which should assist with cooling especially in enclosed spaces. This...
