Converting old Raleigh 3 speed

Here is a review I just found of the TS250w posted on my birthday, 12/17/2018.
Good review of earlier version.
he says because of torque sensing the brake cutouts are not necessary, hmmm. What do you think folks?

Tongsheng TSDZ2 review: great value but not without problems

This Tongsheng TSDZ2 review is based on my experience installing over 30 of these motor kits on bikes as diverse as road bikes, mountain bikes and recumbents.

That's what @PedalUma said about 30 or 40 posts back, IIRC.

What price peace of mind? I’d rather have a way to cut the motor than risk having the motor run on

Stop pedaling and you will smoothly coast every time. The 'throttle' is in the pedals with a robust torque sensor. The whole feel is natural. You can always power down a notch or two, even to push all the way to zero or in a highly unusual emergency turn it all off with one quick touch, but that never happens. The brake levers are not in the game of a six-pin build. Yet, the kill switch is always ready as Mr. Justin-Case quotes from his anecdotes.

Good for you, when I replaced the cheap nasty Bafang ebrake handles that came with my BBS01 kit I fit ebrake sensors to better quality brake levers. When I wrote it up in a blog post and posted it here on EBR, one of the mods commented he liked that because many conversions he sees omit ebrake handles or sensors, I was surprised to read that as they are a safety feature.

Ya gotta stop when ya least expect it sooner or later.

So the eight-pin is essential.

Do both the six-pin and the eight-pin provide for brakes or is it just the eight-pin, pal?

 

[Antonella]

The six-pin is so simple. The wire is so thin it blends in. And you can get the thumb sized VLCD6 which you will rarely look at as you will ride by feel, intuitively. Here is what it looks like on a bike. See how clean the cockpit looks. And another photo or two from the fog ride yesterday. The TSDZ2 36V 350W kept up with the more expensive bikes from stores. Finally you can see the VLCD5, its remote, throttle, light kit, speed sensor and levers. This is how it looks on a bike, cluttered even without the throttle and levers.

I like the set you show. Very minimalist and not something you need to look at constantly I presume and as you say so maybe I don't need the big screen. I guess like driving a car you only
need to glance at the speedometer and your "gas tank" once in a while.
I wonder the difference in font size between them. For people who don't want to wear prescription glasses when they ride, that is important to know.
I like a throttle, the lever one looks nice.
Does the screens have throttle buttons on them?

Are you a licensed business? Not to be rude but you make recommendations that could crush a business for suggesting no safety features, like brake cutouts. Please understand I find your posts invaluable. But a shop could be sued and lose it all.

 

[PedalUma]

As @EMGX said, 'Throttle and the brake motor cutouts/inhibitors are optional on a TSDZ2. Most kits don't include them, only the large screen VLCD5 even has ports for a throttle and the brake motor inhibitors.'

The six pin does not allow for cutout levers or throttles. That is how they are designed and marketed. The brick display is eight pin. It has ports for optional levers and a throttle, plus USB for charging devices such as a phone with navigation, and more programing options. Pick the options that you want for how you like to ride. The owner's opinion is the only one that matters.

 

[EMGX]

tomjasz keeps reiterating this misinformed concern. Yamaha, Brose, Bosch, Shimano - all top tier/big name torque sensing mid drives on premium ebikes - don't have brake cut outs either - because they don't have throttles and aren't cadence based systems. Are bike shops that sell these premium brand equipped bikes "crushed for suggesting no safety features, like brake cutouts" when they sell one of their ebikes? Of course not.
Don't take my word for it, even though I actually have a Yamaha mid drive bike, read this.

How does Bosch sense braking?

I just had the hydraulic brakes replaced on our tandem and there are no wires coming out like some other e bikes I have had. how does the system know when your braking?

Nuts! We’re not discussing LBS sourced eBikes. We’re discussing kits.

I don't know you, but you seem pretty conservative about the bikes you work on, and since many Bafang builders aren't, I have to respect you for it. I hope your clients do. They should.
However, if the big three don't use brake cutouts, there isn't much chance of a liability issue for a kit builder that doesn't either. You may still get sued, this is still America ... but you shouldn't be liable.

That's immaterial, the TSDZ2 and others mentioned in the post that I linked utilize the same type systems. Not the Bafang type that you are most familiar and with which you apparently form your knowledge base. If you know of some deficiency or defect in the TSDZ2 that makes it dangerous to utilize vs similar Yamaha/Brose/Bosh/Shimano systems then that would be helpful information to share. Otherwise you are spreading misinformation - that might be the norm on sites like endless sphere but electricbikereview deserves better.

Once you ride a torque sensor bike with a coaster brake only - No Levers - you begin to pick up on the fact that it works great with out the levers. These coaster brake systems are six pin only so a throttle/levers are not an available option, nor is walk assist. I do not see how the option of adding a cutoff lever to a handlebar could add to safety to a coaster brake only bike. These bikes are super fun to ride. I just rode one moments ago to pick up tubes.
Some people at onetime would remove the brake cutoff on throttle/cadence bikes so they could do burnouts and doughnuts with the non-drive wheel locked. One guy thought he was brilliant for using a zip tie on his throttle at full open all the time, while depending on the levers to cut the power. These sorts of things just are not possibilities on the six pin torque sensor motors. These bikes are sedate and intuitive to ride. Civilized and smooth. No lag and thrilling surge. I asked him if using Duct Tape would be more Hee-Haw than a zip tie. The best clean builds are zip tie free. Zip ties are the new duct tape.

Which of them will be used to build a 3 speed Raleigh eBike?

Yes, I’m conservative. I’m convinced the kit builders with Ludicrous leaning sensibilities will bring on more stringent regulations. I guess I shouldn’t be to concerned as I’m rapidly approaching my dirt map and will no longer support BBSxx customers as of 10/1. Enough. I’m losing my sense of humor.

Good advice “Show ignored content”

Never ever show ignored content. It’s worse than CNN or FOX.

As if that is pertinent, now you're just being ridiculous.
