My first disc brake experience was with a cheap mechanical disc brake, and
braking performance, by any measure, was on par with cheap caliper or
v-brakes. They'd stop the bike as needed, but I didn't observe any
advantage with them. I then upgraded to some Shimano XT hydraulics and this
is when

Just think: a Hunqapillar or an Atlantis with hydraulic discs, front-wheel
swap-in electric motor, and full-time concierge parking service, and most
radical of all, *no second top tube!* C'mon, Grant!
Seriously, I can believe you. I've not tried hydraulic discs except for the
one time I sampled
What are you trying to stop with them? I've got 1.5 hydraulic brakes

Bob Yak trailer) and I spent some time with them on a regular bike but
didn't really see any difference between them and the mechanical discs I

I agree. As I've been attempting to perfect my bike stable, attempting to
have the least amount of bikes for all my possible riding, I've found

I would buy a Taiwan 650b plus Hunqapillar with disk brakes. I know Riv/Grant
isn't thrilled with disks, but they're pretty much the future for bikes
intended to tackle dirt roads. I know some folks perceive them as more complex,
but after some time with mechanical disks on my folder I've found

Phillip,
I suppose I see your point. If Velocity stopped making the cliffhanger
(as they did once before), you'd kind of be screwed. That might actually
be one of
A Hunqapillar made by their excellent Taiwan manufacturers at ~$500 to
$1000 lower price, while still making sustainable revenue for Rivendell
would also be nice.

Not BITD - today and for the foreseeable future! Here in Toronto - like
many other big cities I would guess - both e-bikes and e-mopeds are
plentiful. They are allowed in the bike lanes and don't require a license
to operate.
I agree they have certain benefits to providing greater utility and

Hi -
At the outset, I should state, that I would not buy a bicycle with an
electric motor.
I am not without experience in the world of electric vehicles (known as EVs
in some circles). I think EVs are here to stay. I invested in Tesla. I
currently drive a Nissan Leaf. I don't think a Leaf is
I-phones, e-bikes, o boy! I think any bike designed around a specific motor
system will indeed become obsolete sooner than later. And so the
10-year-old bicycle in the back of the garage will have more in common with
a computer sporting a floppy drive than a vintage Bridgestone XO-2. Though
Whatever floats your boat , enjoy the view .

I'd just like to say I appreciate everyone's comments on this topic, and
realize it's a touchy one for many. My goal isn't to hijack a Riv forum for
ebike talk, I'm just chiming in about a topic that has come up several times
recently on The Blahg. Ebikes are THE big discussion in the bicycle
I also have a Haibike from Germany with a Yamaha mid-drive built into a

Here's a link to the place I got my folder, which will give you an idea how
these kits fit on standard frames. My folder started with a small battery
That's kinda neat. I didn't realize there were any mid-drive kits that
could be retrofitted to a normal BB. All the mid-drive setups I've seen

ones that go through our shop).
Still, it would be best if the battery were

I haven't even read the blahg yet but will say that, as a reformed

when they become cheaper to buy there will be many, many more.
If ebiking makes cycling approachable to more people, I'd welcome it. More
I should correct my original post after reading the BLAHG again: Grant
references not thinking this would work for them. I implied they might possibly
do it someday, which is not correct.

Mopeds were slow motorcycles you could only ride by using the throttle. The
pedals only existed to qualify it as non-licensed back in the day, you couldn't
actually use it as a bicycle. So the comparison, while pithy, has nothing to do
with the question I asked.

Mopeds just won't stay dead, will they? It's nice that this generation of
them are battery-electrics, but an electric Rivespa will never displace any
of my clutter of pushbikes.
