Re: TSDZ2 on a Cannondale Trail 7

It's a mid drive that uses the bike's gears. It doesn't care what size the wheel is.

If you're happy with the TSDZ2 and you don't mind its tendency to break off a crank without warning, there's no reason not to use it. I personally would not touch one with your mother's ten foot pole.

Re: Bike stopped and motor feels weird

Does the resistance ease up when you unplug the controller? If so, you burned the controller. If it's the same whether the motor is connected or disconnected, you burned the motor.

Re: The Specifications needed / Your suggestions appreciated

To noisy when under a load and climbing BBSHD is quieter than most hub motors. I don't know what you expect, but if you want 35 mph in a bike that can climb steep grades, you're going to be able to hear it. The quietest option would be a 3kW direct drive hub with a sine wave or FOC controller, but ...

Re: Are these wheels not laced properly?

The bigger the hub, the smaller the rim, the more it's satisfactory to use radial lacing on a drive wheel. I have had no problems whatsoever, or even maintenance, with my radially laced 20"front wheel with a big Crystalyte 5305 hub that has accumulated many thousands of miles. Those look like t...

So? What have you done? Let me guess.

Nothing?
And this idea you had about lowering center of gravity not improving stability was just laughable.
That only works for multi track vehicles. But thanks for playing!

It gives a very shallow, top-level understanding predicated on a bunch of other arbitrary and fashion-driven bike geometry assumptions.

Why don't you demonstrate these ideas you didn't come up with instead of declare them like they're true (when you don't actually know)? It's common knowledge. Here is one such example discussing the relationship of wheel diameter and fork offset to trail. https://www.pinkbike.com/news/To-the-Point-...

Re: Are footpegs superior if you don't pedal?

Changing tire diameter affects trail (small diameter tires reduce trail and large diameter tires increase trail) so that different fork offsets and/or head tube angles have to be used in order keep trail within the narrow range for the intended application. If you'd actually made things and tried t...

What are you talking about, kid? Build a few unique bikes from scratch and then get back to me. I've been doing this stuff since the '80s. I only suggested an easy experiment that you could use to step up your game. I don't assume you are capable of more than that.

Re: Does my brand new hub motor have a bent axle? (4K video)

If the axle isn't bent, but there's a misalignment between the axle and the motor, then the motor will wobble left and right. This can be corrected by shortening the spoke on the side of the "too close to the centerline" wobble and lengthening the spoke on the side of "too outboard&q...

Re: IGH’s (Internally Geared Hub’s) - Sturmey Archer, Shimano, Enviolo, Kindernay, Rohloff

This would also allow me to use a shift sensor on the cable. All the relatively recent two-cable hubs have spooled cables, meaning they both move together. You can use a shift sensor with any of them. Some ancient 5 speed Sturmey Archer and Sachs hubs use two cables to actuate different parts of th...

http://www.geminusbikes.com/ It is a very special case but it is only possible using a pedal operated generator. That's not true. Sociable tandem trikes have been around for generations. You can even build one from purchasable plans: https://www.atomiczombie.com/wp-content/uploads/2018/08/KyotoCrui...

This is an easy experiment you can do yourself. Get a beach cruiser or other simple bicycle that rides nicely, and try it with different size wheels.

My BBS02 ran way faster than that on 48V. Like 130ish RPM? Faster than I could spin with the stock 170mm cranks. I had an easier time keeping the motor in its happy place once I fitted 152mm cranks.
