comment How to move a bicycle by bicycle
If you walk very slowly, it's easier to hold by the stem, holding the saddle seems much easier for a quick walk (though my experience of walking bikes for any distance is restricted to bike with flat(-ish) tyres).

If you're going to do this, really take the wheels off first, it will make you much narrower. But you might want to wrap the chain in plastic.

comment Choosing an e-bike for commuting
I'm jealous. There's a semi-serious effort to get them on some of the buses on the steeper hills round here, but it's not going anywhere.

comment Choosing an e-bike for commuting
I'm lucky in that my good route is very close to the most direct, but I agree with the sentiment (though I don't think I've been within 1000km of Vancouver). When it comes to buses, you're lucky if the bus can carry bikes at all -- I don't know of any normal-service routes in the UK that can take even a single bike, so I imagined locking it at the bottom. That downhill at the start of the return trip should give a decent boost, getting you closer to the stated range, but I agree that it probably won't make the difference.

comment Choosing an e-bike for commuting
That's interesting, it comes in a few km more than my google bike route, but looking at the capacity (of the bike under consideration before edits) it should be OK with pedalling. Some models have and option for a larger battery pack, and a bike with regenerative braking would charge on the way down for the rest of the ride home. Another options may be one considered by a friend for a steep but much smaller hill: ride to the bottom and get the bus up.

comment Want to start cycling, is this a good bike
Well it's like a chepaer version of what I now commute on, probably good round town, but it's not a 100mile race type of bike, and there's a significant discrepancy in the specs: the blurb says 24 speed, the details say 16speed, with a 50/34 chainset. That's nice on the flat but not a chainset for steep hills. Also if you can't ride properly, you won't want to be hopping on and off curbs, instead get the hang of the roads, including picking routes.

I've answered your question below, because I think it's interesting and I think I've got something useful to contribute, but you might consider making the question more about e-bike commuting and less about shopping recommendations which don't always go down too well.

comment Use a lock nut on a presta valve?
Heavy-handed is almost compulsory when using some of the little frame pumps (of course the solution is to get a better pump, as I learnt).

comment Use a lock nut on a presta valve?
But if you only do the nut up finger tight in the first place, before the tube is hard, you gain the benefit without the risk. My schrader tubes have nuts now as well and it does make getting inflation started easier (probably even more so than on the prestas).

comment Speed improvement from hybrid bike to road bike over 9km at 30 kmph?
@andy256 I would say that this is even more important on a road bike -- you can get away with a lot more regarding stem/top-tube length on a hybrid than tucked into a road bike. My limited experience of my commute on a poor-fitting road bike is that it was slower than the hybrid, though I have to admit I stopped borrowing it before I was completely used to it, and the gears weren't ideal for the hills on my route.

comment Removing Seat Post rusted into downtube
@MadsSkjern at the very least this allows it to work its way in from both ends, but also you can flood the problem area without too much getting elsewhere in the frame.

comment My BionX system won't work in assistance mode, and makes a weird noise
@ÉmileJetzer as you've had the wheel on/off a few times that deals with my other idea: parts that only touch with weight on the bike. I've never heard of a freewheel failing be=cause of removing the wheel from the bike, and I'd expect that to be detectable at lower speeds as well. Another thought - there must be a cable to the rear motor - I'm wondering about damage or dirty contacts in any connector you need to undo to take the wheel off.

comment My BionX system won't work in assistance mode, and makes a weird noise
Is BionX a form a pedal-assist (sensing your pedalling to know how much power to provide)? There are a few ways of doing this but most involve fairly tight tolerances - it could be that a sensor part (similar to a bike computer pickup) is touching something it shouldn't rather than being picked up by the other part of the sensor. Just a guess, but I've fiddled with a couple of electric bikes recently.

comment I want to weld or braze the pedal to the crank arm, but what metals are they?
Rather than epoxy polyester resin (similar to car body filler) holds a thread better. Probably still a temprorary repair though. Sold in the UK as "plastic padding" or "chemical metal".

comment Carrying Pizza on a Bicycle
I've done this successfully (2 boxes stacked) but you do need a fairly wide flat rack (Topeak Super Tourist worked for me), but I wouldn't like to try it on my current Tortec velocity hybrid until I make some mods). I always carry a metre of 3mm shock cord in my tool kit, with loops tied in the ends - perfect for pizza boxes which are crushed by anything stronger.

comment How to fix V-brakes
It's just possible that the cable is so slack that the brake sits back against the fork when you release the lever. You might hear something then. With wide rims you could still be able to brake though not very efficiently.
