Bike lights sure have come a long way the last few years. They'll see you coming with that one
I've had 3 years and some 9000km on e-bikes. The folding models in my case. Jerusalem is incredibly hilly and it's a great tool. My current bike has a 48V battery in it, no 25km/h limiter and a thumb throttle which is nice (though somewhat illegal). I've had to give them up for the moment due to health issues and am now commuting using a car My battery is 13.5 amp which will give me about 40km distance due to the hills. Unfortunately battery life drops linearly from my experience and 3 separate batteries so that after a year of constant use it will give only 60% of the charge that it once had even though the battery is rated for about two years worth of charges.My biggest problem with these bikes is that the are mostly not built to handle the power on the road, at least not the ones I've had. The brakes and tires are too small, suspension not sufficient and when you are keeping up with road traffic at 50km/h, indicators and brake lights become a must as well as a good set of mirrors. I'd also question bike helmets protection at those speeds. I've fallen off a few times during those 3 years and with narrow lanes and almost no bike lanes in this country, commuting at that speed and without proper equipment is a real worry, a fractured knee was the last result of a fall (the one time I didn't put knee guards on!) and I've had to replace 3 helmets. Recent models released here are equipped with (much) wider tires, have dual hydraulic disk brakes, a brake/indicator light system and dual mirrors as standard. I'd like to build a 'proper' e-bike one day for myself. Based on a mountain bike system with a mid drive system and with all the extras I believe are needed. One day.

Those 50km/h E-bikes need to be registered as mopeds here, and are mostly not allowed ride on what we call "light traffic lanes", which are meant for pedestrians and bicycles, also you will need a proper motorcycle helmet.I'm quite happy with the 25 km/h limit, the E-bike still cut my commute time in half, and I specifically wanted a quality factory built bike with Bosch motor and battery for longevity. Not cheap, but as they say, you get what you pay for I ride about 2500+ km a year just for my commute, all year around, sometimes in 15 cm of snow in the winter, which is where the E.bike will help the most Edit: No disrespect to your bikes at all, I've not ridden them so I wouldn't know

The bikes here with their thin tires are treacherous enough just in rain. That's what fractured my knee. First rain of the year, wet and slick with a years worth of oil from the road. My bike can't do 50km/h on it's own but on a flat and with my pedalling, it's quite easy to get to. Heck I keep the power on 3/5, full power scares the heck out of me.

That's why we have 2.25 inch studded winter tires for, riding on snow and ice (around 400 studs on Schwalbe 29" Ice Spiker Pro's). Also my summer tires are Schwalbe 2.35" tires, no problems in the rain.PS: I actually went 49.5 km/h today on a steep downhill, it gets quite scary...
Probably next month I will buy the winter tires for the E-bike...Schwalbe Ice Spiker Pro Performance:(Image removed from quote.)400+ studs on each tire...I've been using these for years, and they are extremely grippy on ice, on snow and decent on bare asphalt (except of the noise they make on it)As far as I know, these are the BEST winter tires in existence

Quite a few times I've thought "ok it wasn't all that slippery today" only to step off the bike and have my shoes slip on the ice
Have you got any suggestions for really grippy tires for rain and general oily roads?
Quote from: pomsbz on August 31, 2017, 08:51:07 AMHave you got any suggestions for really grippy tires for rain and general oily roads?What size wheels/tyres?
My recommendation would be wither Schwalbe Marathon Plus (nice pretty much indestructible tire) or Schwalbe Big Apple (nice cushiony ride)Both with quite minimal pattern, since basicly a slick tire would be optimal on tarmac, just different in which one is more important to you, durability or ride comfortability That said, it's all depending how wide tire your bike takes...Few are shown in here, just choose the right tire size
What's the ETRTO number (something like 37-406) on the side of the tyre, and what have you got on there at the moment? There are a few different 20" sizes out there - the 406 is the most common I think. You don't need tread on tarmac, and nothing will grip on oil. Schwalbe will probably make something suitable - Marathon, Marathon Racer or Kojak, depending on what width you can fit in your frame. I like Panaracer - they make the Minits and Pasela that look like they will work. Or Continental Contact/Contact Speed.

Thanks!Although a slick tire is good on tarmac, I'm specifically looking for one which will grip the road in rain. I know treads won't make a huge difference for that but is there other technology which might help?
Unless you really need the total puncture proofing, if Street clear of the Marathon Plus. Too heavy, too slow.

Too heavy, too slow.Keep in mind that I've travelling up to 50km/h. That's about 30mph. It's one of the only one Schwalbe recommend for motors that go up to that speed from their own line. Not that they have them in the correct size so it's rather academic
