    Long Term Review of the Magnum Ui5

    I have posted some impressions of my Magnum Ui5 on here in the past, but now that I have owned the bike for over a year, I thought it might be time for a review based on my long term experiences with the ebike. In the past year I have ridden over 2500 miles on my bike, and my wife has put over...

    New Battery technology from MIT

    This could be really good news in a few years when it trickles down to ebike batteries: http://news.mit.edu/2016/lithium-metal-batteries-double-power-consumer-electronics-0817 Some folks at MIT have developed a new Lithium battery technology that offers twice the energy storage for the same...

    homemade electric tri-bike build with my 6 year old nephew

    I would also maybe try and get him a helmet...he is moving pretty fast on that trike!

    Would there be interest in a forum topic dedicated to guest/user reviews?

    The solution Court came up with was just to make the Brand and Type discussions more visible. To find out if there are any user reviews for an ebike you are interested in, just go to the Discussion by Brand & User Reviews section on the forum...

    Please help choosing ebike for cold climate

    It is perhaps an unusual suggestion, but for riding in snow and ice, a recumbent tricycle makes a lot of sense: All of that slipping and sliding looks like fun when you have three wheels instead of two!

    Review of High Performance Ebikes Recumbent Tricycle Conversion

    And for something completely different, here is a propeller you can put on your bike: They stopped making them....too noisy and not nearly as efficient as a hub motor.

    Trying to decide which way to go with first E-Bike

    A good place to start looking are the electric bike kit reviews on here: https://electricbikereview.com/category/kits/page/2/ There are lots of mid-drive and also rear hub conversion kits you can add to your trike. One of the best DIY mid-drive kits is the ERad kits from LectricCycles...

    Does using throttle to start from dead stop harm the controller?

    Again thanks for the info. I do start pedaling almost immediately. I just like to get my foot on one pedal, then hit the throttle to start rolling, and then I immediately start adding some leg power. I do always try to get into a lower gear as I am coming to a stop. And I have not noticed the...

    Review of High Performance Ebikes Recumbent Tricycle Conversion

    I hear you about the whole legality question. I talked to the owner, Paul, at length about this. He had some interesting anecdotes. He took his 10,000 watt ebike that will hit 50 mph in less than six seconds to the DMV here in Arizona asking if he could register it and get a license plate. They...

    Trying to decide which way to go with first E-Bike

    Have you considered adding a mid drive to your trike? That might give you the best comfort and yet also the added ability to go further and climb hills.

    Nuvinci n360 equivalent gear ratio

    If you know the number of teeth on the front chainring and rear cog, you can calculate it easily enough: # of front teeth divided by # of rear teeth x 0.5 x size of the wheel is the lowest low gear of the Nuvinci # of front teeth divided by # of rear teeth x 1.8 x size of the wheel is the...

    Does using throttle to start from dead stop harm the controller?

    This thread on a recumbent bike forum has a post (by marc S.) that suggests it is extremely hard on a typical controller to use the throttle to start up from a dead start: http://www.bentrideronline.com/messageboard/showthread.php?p=1441506&page=2 Does anyone here have a perspective on this? I...

    Review of High Performance Ebikes Recumbent Tricycle Conversion

    It struck me that this kind of high power system would be ideal for fat tire trikes. Just like fat tire bikes, the large tires do slow them down, only more so because they have three fat tires instead of just two. Here is one: http://www.utahtrikes.com/PROD-11619824.html

    Review of High Performance Ebikes Recumbent Tricycle Conversion

    I just spent the afternoon with Paul MacDonald of High Performance Ebikes checking out his electric conversion of a KMX Typhoon recumbent tricycle. The quick take is that it made me feel like a 12 year old kid with the coolest go-cart in the neighborhood, and maybe even the entire country! The...

    Two Speed DIY Hub

    This is an interesting concept. My biggest problem with my hub motor ebike is very occasional overheating on big hills. I do not really care about how fast I get up the hills around here, I just do not want my motor shutting down part way up. So if this would give me a low range for climbing...
