- I will show you how to eliminate ghost pedaling E-Bikes.
My Lectric XPedition is so much better now.
But this will work on any bike.

Most bikes have 14 tooth high gears. 11 makes a big difference.
A reason why the chainring is small is to get you home if the bike malfunctions or runs out of battery. Many people won’t be able to pedal that 58 on a dead bike. So then you need to change the cassette to one with a climbing gear. Just something to keep in mind. I had to limp mine home a mile when I had a sensor go out.
What i just see... front chairing uppgrade from 50 to 55 gets gear ratio up by 10% and change a casette small ring from 14 to 11 ingease it about 30% without degrease ground clearanse and no need to extend chain. There is lot of charts and calculators to count you gear ratios and speed vs cadece in different combinations. So if you want go fast without spinning like crazy change caset instead of front chainwheel. It is just math and physic.
When I switched out my cranks, I changed out chainring to a 69t Driveline. My tiny Swagtron EB7 used to top out at 18.6. Changing some P settings, performing a shunt mod, & the larger chainring means I’m ghost pedaling after 28.4mph. 72v conversion coming soon to replace the lethargic 36v system.
My e-bike came stock with a 42T chainring and a 14-28 freewheel. Ghost peddling started around 20 mph. To make matters worse, it has a torque sensor which I love but was useless once the ghost peddling started. The torque sensor requires pressure from the peddles to call power from the e-motor. No pressure sensed (ghost peddling) no power assist. It was impossible to see that class 3 28 mph the the bike was capable of without peddling like a mad man with the torque sensor due to the ghost peddling. According to the cycle/gear charts, it would take a cadence of 105 to achieve 28 mph. That's unreasonable and unacceptable. So I replaced the 42T chainring with a 52T one, and the 14-28 freewheel with a 11-34 one. My 1st gear ratio is the same as the original so no change there. But my final drive, 7th gear is way better. My new 4th gear is about the same as my old 7th gear. Ghost peddling has been completely eliminated so I now get power from the motor all the way up to 28 mph. And when I get there, my cadence is only 65. Perfect. 🙂
This is very important for E-bikes with 20" wheels
I have a m620 mid drive and a 48tooth chainring..I get ghost pedal around 24mph..you think going to 58 is worth it
there is a 9 tooth,probably not on a freewheel
Can't imagine needing more than a 52t chain ring with 11t high gear on the cassette to hit 28mph. And that's if a 52t will fit on your bike. It may hit your chain stay before you can get it all the way on. Not all chainstays are shaped the same. A bigger chainring will give you more top end speed on flatter ground but can also make it tougher to get up hills unless you got some good motor power. So it's a trade off. All depends on what kind of riding you do the most.
I added a 58T to my 20” fat tire Ebike and had to do nothing with the chain. Wrapped it right around the new chainring.
I have seen the evolution....very impressive!
You make it look so easy!
Great to know when we get e-bikes. Trying to decide which ones to get. We have lot of trails, dirt roads, hills, etc in Alabama. Would like it to go through sand good when I go to South Florida. Thanks for the video.💥🚴🏻♀️😎
Hi Gary a neighbor from the north here. My e bike has a stock freewheel of 14-34 and to change to a new freewheel of 11-34 is a big improvement to minimize ghost pedeling. I am ok with the stock front crank ring. Good videos Have a nice day. Tom up in Canada in the Maritimes at the NB-NS border.
I’ve heard that the bigger front gear makes it difficult to peddle the bike At lower speeds. Can u confirm this or share some information on this. Thanks.
So the pedal arms clear the frame ok? Great video. I like to pedal too!
Those fold up peddle are of interest to me. Where can I find those? Also looking for some 10 in X3 inch tubeless tires for an e-scooter. Current ones are 2 ply, I want 4 ply, and if a higher profile adding to the circumference, so much the better. I am in Costa Rica and many uphill grades of 30 to 35%. One at 41%. Without peddling my e-scooter does 38 KPH on a 21% grade.
If everyone is going to 11 tooth freewheels or cassettes, there may be a reason...
does it matter which bike you do this to? (adventure 2?)
I am running a 75 tooth chain ring with an 11 tooth freewheel on my wired freedom…I just ordered a 90 tooth chainring crazy lol
