"That quite alright, Robin, my boy" To the Bat cave to get into your camera settings and raise or reduce (experiment in the lack of a manual) the I.S.O. setting by a few points at a time. I.S.O is the sensitivity the camera sensor has to ambient light. It depends on the make of camera but usually a slightly lower I.S.O. will make the camera adjust less to low light situations (like sitting in the shade of the ol' oak tree) preventing it from becoming washed out.

Hey Micah, great video and very informative. I want to add a bit about wind resistance and cost. I am on a 3kW Cyclone ebike generator (800W) hybrid where generator is removable for different modes. Also, don't take this as me grand standing I just have a lot of time to test and think about this. I would say that 22 mph is the sweet spot for ebikes from a wind resistance and cost perspective. To get there you need 750-1000W motor. The reason why that is the sweet spot is wind resistance robs a lot of power and becomes to the 3rd power above 20mph and 750-1000W motors and batteries are relatively cheap compared to 1500W+ kits. I rarely ride at 3kW because it is so inefficient due to wind resistance and battery life. Of course if you have an unlimited budget just go buy at 72V 30ah+ battery and you can go at whatever speeds you want. Can't wait to see you on the Harley Livewire btw.

I upgraded the battery to 48v the controller to 800w and stuck a cycle analysist I there for good mesure, now I have a bike that can go 30mph and has great acceleration and hill climbing ability’s. If I creep to the uk leagal speed of 15mph then no matter how steep the hill is I can go up it at 15mph. At peak current draw the CA was measuring 1500w.

The more power thing isn't for top speed it's for acceleration. My ebike was bought as a 200w and I ran it for about 7 years. Then I decided to upgrade the hub motor to a 1500w. Yes the top speed is over double of what it was but you don't really go blasting along at max speed on the public highway. It's the acceleration & unassisted hill climbing that's awesome. It's like getting out of a Trabant and into ANY modern car. The difference is mind blowing.

Since there was a statement in this video that 200 pounds rider barely can climb hills w/ 500w motor - I’ll say - I’m over 200 pounds and even using only 2nd power-assist pedaling level I’m able to climb very steep grade not only without problem but with acceleration. Using only $500 Haybike Race Max e-bike sold on amazon I have enough power and acceleration shifting only between 2 of the 3 available power-assisted pedaling levels. Never ever I needed 100% pure throttle in order tired already to ride my e-bike and just so you know I’m 75-yr of age senior.

I've got over 18,000 miles (28800 km) on my 2003 LWB recumbent ebike build. It uses an old fashioned (with modified slightly lower gearing) USPD Currie drive on the rear 26" (41.6cm) wheel. The motor/controller is rated for 48V, 1000W continuous, 1500W peak. You might get the idea from this that I never pedal and only ride it with POD (Power On Demand) throttle wide open all the time, but nothing could be further from the truth. I always pedal and seldom exceed 500W of power even on one of the many 15%+ grade hills in my territory. I use no motor power on flats or gentle rolling hills. Having the extra power comes in very handy when I take the lane in traffic in areas where it's stoplight to stoplight every block. Having all the surplus continuous power while rarely ever using more than half of it means I don't stress the drive too hard at all. That's probably why the longevity has been so good as it shows no sign of lower performance today, 16 years later. Here's a picture of it from back in 2003 after I completed the build: tinyurl.com/y2subu22

@@JaleelJohanson62 Pity the link doesn't seem to work at the moment. I wish there were more people like you. Over here in the EU you can use a speed-pedelec, but then you need to have it insured, wear a helmet and have at least a drivers license for a moped (which is quite easy to get). Any car drivers license will do as well. More and more people are getting rid of the car and commute by speed-bike. Far more popular though are low powered e-bikes (rated 250W), often called pedelecs. Anybody can ride them, even children, and you don't need anything. No license, no insurance and you don't have to wear a helmet. Nowadays most of them are 36 Volts and they are fused 15 Amps. This means the maximum power is up to 540 Watts (and the rated 250 Watts is defined as the average maximum). Their speed is limited though to 25 km/h with a 10% window, so most of them easily go 27-28 km/h. You can tweak them to go much faster, but officially those tweaks make it illegal to ride on public roads. There is no throttle (by law), you'll have to turn the pedals. There are 2 systems: one that only checks whether you turn the peddle (no matter how slow) and one that adjusts the power of the motor to the force on the pedal. The latter gives a more natural feel, the first makes it possible not to use any human force at all. To get back to the title of the video. An average adult of 80 kg riding a normal city-bike on a flat surface at about 18 km/h uses between 80 and 100 Watts. Living in the Netherlands we know all about bikes and we are so very lucky not to have any hills, let alone mountains. Our biggest challenge is peddling up a bridge.

@@czarzenana5125 Our laws here in the U.S. regarding ebikes vary by state. There is a federal law as well, and while there are some states that follow it to the letter, the federal law is used primarily as a guideline for the importation of ebikes from abroad. In my particular state, the law for ebikes was recently changed to that of mopeds. I have a top speed limit under motor power alone of 30 mph ( 48 kph) with no more than 2.5 brake hp to the drive wheel. One must have a driver's license to ride an ebike on the streets. That leaves those who's licenses have been suspended off of ebikes as well though as well as those under age 16 which is not very good IMHO. I have a velomobile as well and it incorporates the Bafang BBS02 750W mid-drive that powers the cranks in parallel with human pedaling. While it does have a POD throttle, I tend to ride it in pedelec mode as I like that better. It's of the simpler design you mentioned where there's no torque sensor and therefore no varying assist level to match the user's level of pedaling. It's still a blast to drive and I can't count how many times I've been videoed while out and about in it. lol I would think that with a 250W power limit that a mid-drive where the motor can take advantage of the bicycle gearing would be the way to go? My velomobile in the lowest gear could climb a tree if it had claws to grip the bark. lol I've watched many videos of the bicycle culture in the Netherlands and would love to visit there some day!

How was it?

@_deepdigger_6076 3 жыл бұрын

@@01imh Difficult to say: First I tried to make the throttle control via Force on the pedals, but this is at 3kw unbearable(flew off the bike because of too much power).-> To compare: the maximum torque is the same as a 100ps motorcycle. Now I'm controlling it via a real throttle grip and it is much better, also programmed an "Speed"-Mode where it automatically accerlerates me to a given speed if i pedal, but at fixed torque much lower than the 3kw (I guess about 1kW or so). Also I made a extra battery because the normal ones don't give you 3kW To conclude: I freaking nice and has a lots of power, but in everyday use I guess 1kW is more than enough.

@@onepalproductions Yes and no. You can buy motors and controllers from china and use any low end bike to build an ebike for cheap. But you are responsible for picking a reliable source, designing the system and troubleshooting any problems. And, or course there is no warranty or support line. Ebike retailers in the US want to carry bikes with a decent profit margin, because they have ongoing costs to cover. I can understand why they don't want to carry cheap 5kw bikes - in addition to low profit margins, there is huge liability for them.

@SuperSushidog 3 жыл бұрын

Then how about the Lectric XP or ST? They cost $899, and are a class 2/3 e-bike. This means they will go up to 28mph in pedal assist and 20mph in throttle only mode (limited by law). If you want to go faster, the law classifies it as a motorcycle. At that point you need a motorcycle license, registration and insurance, like any other motorcycle. An e-bike lets you avoid these sometimes expensive legal necessities. E-bikes also appeal to those who don't have or who can't get a driver's license, for whatever reason.

@@SuperSushidog There are othwr justifications for high power ebikes. I want a fat tire bike that can baul a small trailer through any weather over any terrain. That require a hell of a lot more power than 500w or 1000w Other people want a bike they can ride levally to an offroad area, where they can use the extra power fully.

@mkygod 2 жыл бұрын

One factor that is not often talked about for ebikes is the diameter of the wheels and how that affects top speed and hill climbing ability. Although you may be sacrificing some top speed, smaller wheels do not need as much wattage to achieve the same torque to the ground needed for hills. Ofc, gearing also plays a big factor in the case of mid-drives, but all things being equal aside from wheel size, i think this holds true.

I'm running a ASI bac 800 72v and a 72v 150amp on the hub. The mid drive display is the NXT touch screen. I'm running two triangular 72v30amp hour batteries. Fast and dependable, both used together on low pedal assist gives me over 200 miles of range brakeing with the regen lever. Two independent drives always gets me home, and usually first across an intersection.

Thanks for the great videos. I have an Ecomotion Core Pro E-Fat bike. It's a 500w 48v rear hub motor. I love the bike but I'm a bit disappointed in the power going uphills. A few fairly steep hills and I have to really pedal away to get up the hills. More so then I was expecting. Can you tell me how complicated it would be to increase to 1000w?. If I have to replace the rear motor that's okay but how complicated is it and does this mean other things like the controller will need to be replaced and if so are there kits for this?. I would really love to increase the hill climbing ability of this bike and I have no idea if increasing the watts of the motor or new motor is possible. I even thought about adding a 500w motor to the front as well but saw a video of a guy doing this and couldn't get both motors to work together properly. Thanks!!
