@ebikedelight delight. Maybe I wasn’t clear. Apologies if I sent you off in the wrong direction. 1) How many teeth are on the chaining? How many teeth are on the freewheel. I.E. How many gear inches does the bike have? (this is NOT a motor related question) 2) I bought a similar ebike...

Is there any information on the gearing? I'm really curious to what that is and how easy/difficult it is to ride the bike without the motor.

Thanks. I think that is about what most experienced people expected. That is about par for a direct from China mail order bike. Give it a few weeks and the spokes are likely to come loose and cause other problems (if my experience is any indication). #1 relates to my second favorite Ivars...

Wrong Surly Pugsley video, you should have posted that video of the fat bike rider, going down hill and successfully riding across a stream.

Nice post! I think you are right, this has already stimulated all kinds of ideas, products and new ebikes. It is great for the market, and the interest it has generated. Realistically, Sondors is a $1000 bike by the time you include the bike, shipping, assembly, and required tune ups. $1200...

I'm an avid cyclist. My first build I rode 24 miles and used about 20% of the battery. Just means I was doing most of the work, not the motor. An avid cyclist can do 100 miles on no batteries. The real question is, what can the bike do without any assistance.

Speed of an electric motor is determined by the motor design (say 250rpm at 36v) and the voltage applied. The only way to increase the speed of the motor is to apply more voltage. Increasing the amperage will increase the pulling power, but will not change your speed. Any hub motor (or...

Sweet! Thanks for sharing!

Yeah, there are 48v problems (as with any hot rod project) - It is going to overheat faster on hills or off road - Who knows if the bike can handle the speed (probably 25mph if it is a260rpm @ 36v motor) - Tires Some of the Fatbike gurus have problems running at low fatbike PSI and having...

Yes, you can get anything on alibaba, although the newer style skinny batteries are probably a better bet. (Link Removed - No Longer Exists)

@EULITTLB - I suspect that most people are quite happy with their bike because: 1) its a shiny new thing (that they have been waiting for) 2) they got the latest toy on the block (think Mr Hillis,, the bikenut from dallas) 3) pretty much everyone here thought their first ride on an ebike was...

$60 sounds reasonable for assembly. Its $50 just for a tune up, and any new bike needs a tune up when assembled, and a tune up after it is broken in. so, $50 for a build. Maybe another $50 for a tune up in a couple of months, or $75-$100 if the wheel needs to be trued and tightened up. My...

Yeah, should add cost of assembly to the realistic purchase price of the bike. I'm guessing at least $100?

Interesting video, thanks! a 60+ lb single speed fat tire bike just wouldn't be my thing off road. The guy on the mountain bike just left him in the dust during the some of the technical parts. I'm thinking this bike is better for or maybe double track gravel grinding. I'm still curious to...

New Storm "Buy Now" option on craigs list:

Looks like it is coming together nicely, although I cringe a little seeing an electric drill being used on the head set. I guess if it is set for a torque of 5nm it should be OK. Its nice seeing a small army of factory workers do all of the assembly that I did by hand on my bikes.

We should rename this thread Sondor's Skeptics corner! @stevenast Yes, Agency 2.0 did an amazing job. I can't see this campaign having generated the money it did without them, and Sondors should be very grateful for their help (I would be in his shoes). They made the difference here...

How much did he sell? 10,000 bikes? Its 40 batteries per bike (10s4p). so, 400,000 batteries at 2.00-4.50 a cell? May be $3/cell? that = $1,200,000. That is the biggest piece of the budget.

Hello my friend, None of us know what cell Ivars is using. However, I recently posted a spec sheet for a cell that matches his claims and his photos. It might benefit you to read Samsung's official specs (rather than aliexpress.com). Charge at 1300ma to 2600mA (0.5 to 1.0 C) Discharge at...

Agreed George. It would cost you or I about $4.50 per cell, Elon Musk about $2/cell. I think it is safe to say that Ivars is paying some where in between those numbers. However, the point is that good Samsung cells cost about twice what a generic Chinese ebike battery cell costs. As...
