How to Lace an E-Bike Hub Motor Wheel. This article is primarily aimed at guiding a less experienced bike mechanic through rim replacement on an electric bike hub motor.

It also can be used as a guide for those wishing to do their own wheel build on a conversion project. I don’t pretend to be a wheel expert. For detailed information on the subjects in this article, go to the Sheldon Brown website. The Ebikingnow Dynamometer - ebiking now. Dynamometers (or Dyno for short) are awesome devices; they provide consistent feedback and results of a motors performance and characteristics.

The Ebikingnow Dynamometer - ebiking now

The fundamental principle of a Dyno is relatively straight forward, where output data calculated is from the rotational speed of an object multiplied by the torque experienced by that object. On my Dyno, I am spinning up a direct drive hub motor that is free to rotate while connected to a torque arm and load cell to measure output torque. I know, I said it was straight forward, but it will be with some simple diagrams! For consistency purposes, let’s call the motor being tested on the Dyno the Drive Motor, and the hub being turned over the load motor. To induce a load to the drive motor, some form of brake is required to slow down the load motor. Power (W) = Torque (N.m) x Speed (RPM) / 9.5488 The Kelly Regen can be a fickle thing at times and for low-powered cycles, the lowest regeneration force seemed to be a little too large.

Torque Vs Wheel size - ebiking now. Motor torque and what the rider feels can be drastically different from one another and depends on several factors.

Torque Vs Wheel size - ebiking now

Motor torque is in the form on Newton-Meters, which represents the amount of force that is applied by a rotating member at exactly 1m from the axis. Now, on a bicycle tyre, the distance from the centre of the wheel to the tire tread is our distance, and for a 26” bike is not 1 meter but a mere 330mm! That means that the resulting force of a motor that is rated to 100Nm would be exerting 303 Newtons at the road on a 26” wheel and 100 Newtons if the wheel radius was 1m (hypothetical of course).

This is why a motor laced to a 20” wheel will feel like it has more acceleration than a motor laced to a 26” wheel, because it does! Electric Bike Review. Upload ElectricBikeReview.com Subscription preferences Loading...

Electric BIke Conversion: Finding the right mountain bike: Part 2 brakes, gearing, wheels. This is a continuation of Choosing a Mountain Bike to Electrify – Part 1 Suspension Frame material- most e-bike gurus prefer steel frames over aluminum.

Electric BIke Conversion: Finding the right mountain bike: Part 2 brakes, gearing, wheels

Why? Steel is stronger and does not fatigue the same as aluminium. Aluminum fatigues and snaps and breaks. Also because of all the weight the electronics add to an electric bike, the few pounds of weight saving you get by using aluminum over steel is not a big deal, and should not be a big factor when choosing a frame. What E-bike kits provide the level of power you want? If you are fairly new to the idea of an E-bike, and you think you might want one, this article hopes to give you some info to help you get some kind of an idea about what type of kit will fit your needs.

What E-bike kits provide the level of power you want?

Factory E-bikes are very expensive compared to the kits that you can get and install on your own bike, but…some people don’t mind paying more to get good customer service from a local dealer, and getting a turn-key factory E-bike that they can begin riding immediately. But…if you are mechanically handy, and can install a basic E-bike kit yourself…the kit ideas below may save you some money. Using a kit will also allow you to use a bicycle frame that you chose yourself…to allow you to save even more money, and to also get a bike frame that is the best possible fit for you. Before we get started, forget about the wattage ratings of the advertisements for these kits. One horsepower is 746-Watts, and the method of rating a kit is to multiply the voltage times the amps. CD00276203. What tires should I get?

It seems like a pretty easy question. Many of us in the market for new gear put a lot of time and energy in figuring out the right bike, wheelset, components or power meter to get next.

Although building your own won't necessarily save you money, there is a sense of pride and satisfaction that comes from building your own light system.

Featured Kit. Getting Away with Riding an Illegal Ebike:10 Tips. With the introduction of production electric bikes that are illegal on city streets because of their high top-speed and power (read our article on 10 illegal production ebikes 2013), it is time to question if and how you can get away with riding these bikes on the streets.

Its nothing new for the DIY ebike community to ride illegally-fast electric bikes on the streets, and some have been using the following strategies for years to avoid getting ticketed…or their ebikes confiscated. Always remember this simple rule: “It’s an ebike…if you can ride past a cop and not get pulled over.” Here are some tips below to help you on not getting pulled over, while other tips might save you after you are stopped. Educate yourself. Specialized Turbo Ebike Review. The huge global bicycle company Specialized invited 30 members of the media to an exclusive ride-event in San Francisco which included: breakfast, a presentation by the Specialized engineers, a talk by the Specialized founder, a ride through San Francisco on 30 Specialized Turbos, and they capped it off with a nice lunch.

Arriving at the meeting place, I noticed that the fleet of Specialized Turbo bikes were lined up on a red carpet in an impressive (and very expensive) formation. At $6000 each that is a lot of cash. This press event is way beyond what I have seen or heard of any electric bike company ever doing. Specialized is big bucks, and knows how to throw a good party. All Products. ELECTRIC BICYCLE.

May 13, 2009 Military-funded projects often pave the way for a much better consumer product, and although the original DARPA funding of the development of the Tactical Electric No Signature (TENS) Mountain bike for Marines and paratroopers is now over a decade old, hold onto your hats folks, because the design has been upgraded and will be sold in limited quantities with a 1000 watt propulsion system.

The TidalForce M-750 x2.0 is based around the commercially available (and ingenious) Montague Paratrooper folding bike but has a top speed of over 30 mph and range on a single charge is 25 - 28 miles, using the electric power only. The E+ advanced propulsion system features nine forward power modes, nine resistance (exercise) modes, cruise control and anti-theft.

High performance needs high amps, but LiPo can be dangerous. High performance requires high amps, but LiPo batteries can be dangerous for someone who is inexperienced with them. LiPo is capable of putting out VERY high current (the C-rate), and if you are building a racing E-bike, they are simply the best choice. A LiPo pack will be smaller, lighter, and will put out more peak and continuous amps than any other pack you can buy. The problem is that…for E-bikers who want something that is much safer, but has better performance than the average common battery pack, the options are not well known.

It is possible for LiPo to be handled safely, but Hobby King sells LiPo in their bare form, with no protective circuitry for charging or discharging, and each builder is the one responsible for adding a BMS and making a protective case, so…sometimes they become damaged and catch on fire!
