I love ebikes and was fortunate to make some expendable income of recent to contract the ebike of my dreams. A mid-motor high torque climbing machine with 10 inch suspension travel to smooth ride on the rough stuff. Can be used for high speeds and motocross but my intent is to use it for getting to the back woods and for site seeing. To climb steep mountainous areas it takes a large motor and battery to avoid over heating. By Vector Bikes GMBH Munich Germany. The motor is actually designed to fit in the wheel with spokes attached. In this case the spokes were removed and it is mounted in center of bike for good weight distribution, less sprung weight at the wheel, and a 3:1 sprocket reduction for high torque/lower top speed. The motor actually rotates in place. My choice on the color scheme.

Nice! For the time of being I still pedal (it's very flat here), but I'm getting older, and on those windy days, the assist would be nice. In Spring, it's almost always a head-wind going to work, then mid-day it switches and it's a head-wind going home. 15-20mph winds don't sound like they'd be excessive, but for 16 mile commute, it's definitely something.
Where do the saddle bags for your coral hook up?

Amazing bike! Somehow always feel safer on a 2-wheel ride rather than 4-wheel-ATV on mountainous terrain, reckon less steel to fall on me.

Where do the saddle bags for your coral hook up? For flat land and heavy wind stephan. Yes, peddling against 15 mph winds require lots of energy. This is a Rad brand cargo bike. Rad is an established dependable ebike distributor. This is a great flat surface bike, note it only has balloonish tires to soften ride for rough ground. It has a 350 pound payload. The range is not reduced much with heavier loads, more so running low tire pressure to soften ride. It cruises at 16 to 20 mph and can be peddle assisted if you want to extend battery and get exercise. It won't do the claimed 45 miles on a single charge unless you peddle assist the motor...about 25 with no assist on flat land. The motor is easily programmed from 20 to 26 mph top speed. I set mine at 26 mph but replaced the rear sprocket cassette with taller gears so it could be peddled at a comfortable cadence at 20 to 26 mph. At this speed the pro bicyclists can barely keep up with you. Be sure to put a massive cooler on the rack when you are passing them. Some get aggravated(actually many) when you dust them on the fully loaded Granny bike he he. I have the old direct drive hub motor instead of the new geared hub motor. Direct drive hub motors regenerate back to battery but at a rather low efficiency. Less torque for climbing hills but it regenerates 20% when going down hills or braking. It may go 15 miles w/out peddle assist and 30 miles with peddle assist on rolling hills. in your future possibly Stephan ? Our bike(wife's choice) with the larger diameter 750 watt direct drive hub motor. I actually ride this one the most, has comfortable seat, more upright reducing pressure on arthritic wrists.

This is a Haibike mountain bike with 500 watt mid-motor. A pro grade lightweight mountain bike with a Bosch mid-motor. The mid-motor design allows the motor power to drive the bike thru the gears for mechanical advantage. In this case the motor is turned on by peddle assisting only. Great bike for those that are more active. If you do not help the motor by peddling on continuos steep grades it will turn off due to an over heat sensor. If rider is in decent shape it will pull 1000 feet altitude in one mile of distance. Perfect for Appalachian mountains where the hills are short and steep but numerous. I got it 'cheaper' because it was a 2 year old brand new bike. At around 58 pounds it is nimble and tackles technical single tracks. Note full suspension with 4 inches of travel. 750 watt motors are the limit for of power for most state and federal parks that only allow non-motorized bicycles.

No thank you.......as long as I can still climb 5 to 7% grades and spin in a head wind at 10 to 15mph........I'll continue using my hard tail.....:
Just ride fewer single track paths along cliff edges........lol

Sweet bike pizzano . Owned that jewel for a long time ? My buddy still has his 45 year old 10 speed Schwinn. We rode in hghschool. Looks like the day he bought it. Owned since brand new 2003.......so it's not vintage nor considered a "modern" mountain bike. More of an all terrain crossover, all Alum, 21 speed w/granny gear. Nothing like my son's high-tech "Specialized" carbon fiber.......lol.....but it's been a good "bullet proof" 20lb beater that takes an experienced rider to perform well on moderate to difficult trails........ at my age and conditioning (given I'm an experienced "rode" pavement slayer), anymore I keep to the wide and smooth stuff. Keeping upright and rolling never a problem, it's falling off and recovery that's a bitch....I'll break long before that bike ever will.........lol

Here's my ride, Blue (yes, I name my bikes), a Kona hybrid with about 100,000 miles on him: IMG_2298_Blue, the Road Warrior by Stephan T., on Flickr Before Blue, I had Sherpa, the cargo bike, also a Kona: IMG_2310_Farewell to Sherpa by Stephan T., on Flickr Sherpa had about 50,000 miles when he was swapped for Blue. When my commute went from four sheltered miles to 16 very exposed miles, 80 pounds was a bit much, even though he was well-geared. He was a work-horse, and was able to easily transport about 250 pounds (in addition to myself). I ran errands that transported wood, large rocks, groceries, cat litter, pretty much anything I needed to. I still miss him sometimes. jamesp possibly that cargo could be in my future, but a ways off yet. One, those things are $$$. Two, I'm an absolute addict about exercise. Not happy if I don't get it. At the moment, I'm still in better shape than many guys half my age, but do have knees, hips and back reminding me of my chronological age. Soooo... never say never.

Although I had/have the ability to track mileage, ect....the only thing I keep data on is everything related to that/today's ride specifically.... no live-span accumulation totals.....got over all of that back when I became "less competitive" in rode cycling.......comfort over pain won out......lol
Nice hybrid's Stephen....Kona made some very good urban crawlers.....there frames are still considered worth the money....!

Nice hybrid's Stephen....Kona made some very good urban crawlers.....there frames are still considered worth the money....! Wasn’t keeping precise data. Just knowing how far I went on a regular basis and how often. “Bonus” trips probably mean that it’s even more than I think. Definitely happy with Kona bikes. Very solid value. Very reliable and resilient. I’ve never raced or ridden competitively. Just functional: commute, gerrands and for fun.

I'll toss this in pizzano stephen. When peddling in peddle assist mode on the street you can burn just as many calories yet cover about twice the distance. Simply exert the same effort as if not assisted. Just saying it is nice to see more sights. However doubling the distance on off road terrain is not so easy on the body parts due to the bumps. And one drawback is increased flat tires with increased distance 150,000 miles is a bunch of miles stephan. Math on that is 41 miles every day for 10 years ! On a heavy bike at that. Wow. If riding for exercise a heavy bike makes perfect sense. That Kona cargo frame is similar to the Rad cargo's. It is interesting to see new mountain bike suspensions influenced by ebikes that have longer travel suspensions in the 8 to 10 inch range. Curious to see if they are implemented on non-electric. Nice to reduce the bumps as much as possible. Peddle assist is managed with a sensor at the crank shaft and magnetic pickup on the spokes. It is quite fluid, like an extension of your body.

That looks so fun!!’ Being electric, you wouldn’t have to pedal. Is that right? Yes that is right Pat. Most electric bikes have 3 modes: 1) You control the motor speed by twisting the handlebar grip for 100% motor power. 2) Or the motor comes on only when you peddle, called 'peddle assist'. 3) The motor can be turned off completely and the bike be peddled like a normal bike. Most e-bikes have 3 to 4 motor assistance settings to save the battery charge. miser mode/full power/etc. They are nice when riding on soft beach sand or in snow. The extra power will help push the bike thru soft surfaces.

It appears the progressive California bicycle youth has engineered this super concise piece of mechanical engineering artwork using repurposed China made off-shelf bicycle batteries, hub motors, front fork assemblies, etc. It appears my German bike may be a copy of this California concept except the individual components on the German bike have been modified for performance unfortunately. Making replacements a potential problem in future availability and cost. Anyway, the mechanical technology is far behind the electronic technology until these California kids entered the picture of recent. These machines have a combination sprocket drive shaft and swing arm pivot point. Quite a concise and sophisticated task. A separate pedaling shaft and peddle freewheel unit. Billet aluminum construction. Single pipe frame. Dual off-the-shelf battery. 3000/5000/6000/8000 watt off-the-shelf hub motor choices. Off-the-shelf front fork assembly. Aftermarket hydraulic disc brakes. Needed upgraded larger chain. This setup for hard core motocross. Same drive system could easily work on an electric ATV or other vehicle configuration. I get goosebumps looking at the brilliant engineering and construction, hat's off: Guessing the original trend setter of this theme is HPC in Chatsworth, CA. It appears the bike above is sporting his billet swing arm and frame. He may be selling components. www.hpcbikes.com/collections/electric-bikesThis may be one of his prototypes:
