Really really nice install! Waiting on mine to arrive on Monday, can't wait to convert my old bike here so now I'm scrolling through KZbin watching every install video I can :) Brilliant idea with the jubilee clips for the mounting in lieu of a hole in the frame!

[@hiphopsuperman]

Love how you shorten the wires. No one else seems to do that and makes it look much cleaner!

[@ElectricBikeLaboratory]

Thank you! Yes I totally agree. The motors come with such long wires to begin with, you end up with an extra 2 feet sometimes if you don't shorten. Appreciate the kind words.

[@VideoMusicManiacPlace]

Cool video. I've been running a Luna BBSHD with 52v Dire Wolf battery for past 4 years. It is a beast.

[@jbaccanalia]

Nice job on the install and retaining the ground clearance most bikes lose with the tsfz2. I'm doing a dahon now and also install it the same way.

[@ElectricBikeLaboratory]

Awesome!!

[@bigpimpin780]

Excellent craftsmanship from an even more excellent guy

[@ElectricBikeLaboratory]

You are too kind good sir!

[@duythainguyen4405]

Thank you for the instruction. I installed the mid drive and trying to get the right hose clamp for it. Everything else is great, it should be done by tomrrow.

[@hillyseattlenarrowstreets6087]

Nice clean build. Hose clamps a must with Tongsheng mounts if you're not using the 2nd mounting bracket. For folding bikes with hinge by water bottle holes, use aluminum square tubing as a riser for Battery mounting to clear the hinge bump. Depending on location of water bottle holes, you may need a Rivnut for Battery to mount better - OR - Ali Express sells $15 battery mount adapter plates which should work. I did a Bafang BBS02 for higher speed and programmed Pedal Assist 1 at 5% so it's slow around pedestrians. PAS 5 is 100% and 20+ mph fast. To get that fast with a Tongsheng, you need A 52 tooth front chaining and lots of pedalling effort. I used a Zizzo Folder on my conversion. A folding ebike is nice because you don't need a bike rack to transport it in a car. Also this bike is much lighter than the 20" fat tire folders - Lectric XP weighs about 70 lbs.

[@ElectricBikeLaboratory]

Great info ! Thank you for the comment ! :)

[@JkLow]

Thank you 😊

[@TheAgentAssassin]

I'd like to see a bafang BBShd on this bike too.

[@specagent999]

Seems like the bottom bracket axle is off-center because the right side crank arm sits further out than the left side crank arm.

[@ioandragulescu6063]

@5:30 very important step putting the thread lock. I didn't and after about 300 kms the setup developed a squeaking noise, while pedaling with the motor engaging (pedaling with no assist was surprisingly quiet). I checked and sure enough, the lock nut and the two M5 bolts were loose. Locktited them and now everything's fine. The only difference is that I've use a LOT of it on the lock nut :). That being said, maybe it is a good idea to run the setup for a while to have everything settle and then loctite and tighten.

[@ElectricBikeLaboratory]

A great point! Yes you're right it is certainly critical, one of the biggest issues we've had is having these motors come loose (usually weeks or months down the road when we first started installing them). Keeping them tight is paramount! You may be on to something with installing it, letting everything settle, and then going back over with Loctite. Thanks for the great comment! Cheers!

[@ioandragulescu6063]

@@ElectricBikeLaboratory well, I am learning too :). Converted my bike about a month ago and now I am waiting for a kit for my partner. But honestly, for how cheap they are, it's worth it (and I like to tinker too). Was cheking some Cubes with the latest Bosch, 4th gen or smth.... 4k ... I mean, that's just insane

[@ElectricBikeLaboratory]

@@ioandragulescu6063 It is insane! Just so you know, the Tongsheng TSDZ2 motors are discontinued, so if you know anyone who wants to get one, tell them to hurry up before they're gone!

[@ioandragulescu6063]

@@ElectricBikeLaboratory crap ... I hope that we will still find parts for them. Is this related to the dispute I read somewhere they have/had with Bafang ?

[@ElectricBikeLaboratory]

@@ioandragulescu6063 Yes, you got it. They lost a lawsuit to Bafang and have had to stop selling the motor on all major platforms, Tongsheng has taken it off their website, most vendors have stopped listing them, it looks like they are no longer being produced. Sad! Because I'm not aware of any other fair priced torque sensing mid drive that fits into a standard bottom bracket :(

[@mandalagan86]

You did a very good Job installing the motorr. I have a bike Friday tourist model. Where do I buy the motor and battery?

[@felixcat9455]

Which model of bike Friday is this? Can it still fold with the mid drive installed?

[@szymonjakubczak5387]

Great idea with the clamps to keep the motor up. I'm going to replace the zipties in my build. What was the length or diameter of the one that had to go over the motor?

[@ElectricBikeLaboratory]

Thank you! The ones that we used were able to go from 3.5 inches to 5.5 inches diameter. Or 89mm - 140mm in normal terms 😁

[@benpar8120]

Great video. Why didn't you put the battery at the back? It would be great to see it folded after the electric install

[@ElectricBikeLaboratory]

Yes great point, a battery on the rear rack makes it more vulnerable to tipping over and then the battery can get damaged if this happens. Centrally mounting is better for center of gravity and "polar moment of intertia" ie makes the bike easier to handle when the weight is centered vs at the back. Appreciate your comment!

[@al-du6lb]

I wish you showed of folded up after the install, but great video!

[@ElectricBikeLaboratory]

Thank you, it did fold up but yes this was missed!

[@al-du6lb]

@@ElectricBikeLaboratory After doing some research, I realize why you didn't fold it up for the video. I was thinking it was more like a brompton, but it's not quite as easily folded.

[@alexmorelli2826]

Same, I really wanted to see the middrive installed on a trifold Brompton style bike to see if it would still fold after

[@mplsmark222]

I’d be careful, that Sachs 3 speed rear hub on this bike is not made for the kind of torque you could generate with that motor while pedaling up hill. Since these hubs were long since discontinued, finding replacement parts are really almost impossible. So, just because you can add a motor, it is not always a good idea unless you are also upgrading the rest of the drivetrain.

[@ElectricBikeLaboratory]

The customers so far have had a few thousand kilometers of riding with the motors and no issues. The motor is not a very powerful motor, so its not delivering excessive torque to the drivetrain. About as powerful as a really strong person doing the pedalling. But I totally agree with your comments, definitely good to be careful not to destroy a drivetrain by adding a motor!

[@cristianharaga3965]

Hi guys Hope you are well,how much a bicycle like that will cost?

[@shawnbrown1404]

Can this be done on a Schwinn Loop folding bike?

[@stuartt5238]

On the controller/display how do you know which of the three connections to use for left and right brakes, and throttle connections?

[@ElectricBikeLaboratory]

Surprisingly the display is really smart in this regard, the throttle is the only 3 wire plug so it is able to detect this and assigns it as the throttle, and the other two as brakes. So you can plug into any

[@ElectricBikeLaboratory]

Sorry, most recently when doing an install the throttle only worked in the middle location, so scratch that last comment! Brake sensors on the ends.

[@mansonroot3200]

Hi! I’m currently installing this kit but have no instructions on which port the brakes and throttle plug into on the display. Does the throttle go to the center and brakes to each side?

[@ElectricBikeLaboratory]

Yes throttle in the middle, brakes on sides 🙂🤟

[@renan3916]

Hello my friend, do you know if such kit can be installed on a brompton?

[@ElectricBikeLaboratory]

I believe so ! Just would need to confirm the Bottom Bracket is 68mm on the Brompton

[@BrentDaughertyMe]

What wattage do you recommend to throttle 20mph+ and PAS 28mph+ on flat ground? I want to convert a road bike. I'm about 170lbs.

[@ElectricBikeLaboratory]

For a mid drive I would recommend at least 500W, but more is definitely better. Keep an eye out for a new mid drive motor coming from TOSeven , it will be torque sensing, affordable and will give the power you're looking for!

[@BrentDaughertyMe]

@@ElectricBikeLaboratory Are you referring to TSDZ2B 48V 750W? I was thinking of pairing that with a 14Ah frame bag battery. I'm trying to keep it stealthy. Can you run the Tongsheng without the screen?

[@BrentDaughertyMe]

@@ElectricBikeLaboratory Just looked into To7. Early reviews don't seem to justify the price increase even though To7 claims it's an improved version of TSDZ2. I also don't need more than 750W for my commuter road bike... too much stop and go traffic.

[@jonk8337]

@@ElectricBikeLaboratory Thanks for your videos. I’ve seen initial testing on different channels. I am excited about the Toseven DM01. I really want a torque sensing BBSHD equivalent. I have 3 recumbent tadpole trikes. A 48v BBS02, a 52v BBSHD and a 48v Falco torque sensing rear hub. I really like the torque sensing experience more than the cadence.

[@KwameGH]

Would a bbhd motor on a steel frame similar to this work out? I want to do a build like this

[@ElectricBikeLaboratory]

Yep it should work

[@jonk8337]

What kind of performance gains are u getting from the 52v setup? Top speed?

[@ElectricBikeLaboratory]

About 45kmhr top speed but haven't been using the Tongshengs much lately and they need the firmware for 52V

[@jonk8337]

@@ElectricBikeLaboratory Almost as fast as a BBS02. Not bad for a budget friendly mid drive.

[@ElectricBikeLaboratory]

Agreed! They did later down the road fall into issues with reliability, the TOSeven motors are just coming onto the market and may be a viable (or better) alternative

[@jonk8337]

⁠@@ElectricBikeLaboratory Yes. They said the tongsheng solved the issues with the new TSDZ2B. I just got an invoice for $630 on the DM01 1000W motor from Toseven to ship directly to me in California. Haven’t bought it yet. I’m still contemplating.

[@ElectricBikeLaboratory]

I've got a DM01 sitting on the shelf soon to be tested out !! 😁

[@10OZDuster]

i have bike s with front hub one a rear hub and one with a TSDZ2....i would have installed a front hub on a bike friday cheap easy quick swapover just a front wheel and the rest of the parts. TSDZ2 on a folding bike friday is overkill.

[@ElectricBikeLaboratory]

Yes, front hub is a good option too. These were for customers of mine, they were very happy with the bikes and had TSDZ2 motors on their other bikes. Thanks for the comment!

[@goretexcondom]

link doesnt work

[@ElectricBikeLaboratory]

Sorry we discontinued this motor at this time! I believe it is still available from other vendors

[@mustaphatahiri1210]

Very good idea to Democrat the electric bike around the world...

[@visualrubble]

What size hose clamp for the motor? 4"?

[@ElectricBikeLaboratory]

3.5 inch to 5.5 inch
