Preparing for hub motor test fit in Leah’s eBike Conversion

The first thing to do with a rear hub motor eBike conversion is to prepare the motor and frame for the first test fit. As shown in the video, the initial preparation includes:

  • Tighten disk brake rotor mounting screws
  • Install freewheel
  • Check width between dropouts, 135mm minimum
  • Check dropout for exact width of 10mm

Disk Brakes

This install doesn’t cover disk brake installation; Leah’s eBike uses rim brakes. For a rim brake install, all that is required is to make sure the rotor mounting screws are snug.

Install Freewheel

Make sure to apply anti-seize or other lube to the threads before installing. This will make it easier to remove water as needed.

Make sure the threads are lined up before threading on. The freewheel should spin on without resistance. If it binds, stop, back off and try again. Otherwise, the threads will be damaged.

Check width between dropouts, 135mm minimum

I’m using an E-BikeKit rear hub motor. It’s OLD (Over Locknut Dimension) is 135mm without spacers or washers. If the inner washer is used, the OLD increases to about 140mm.

For the first test fit, 135mm width between dropouts is enough. If the width between the dropouts is less than 135mm, the stays will need to be spread apart. The width on Leah’s bike turned out to be 136mm so I don’t need to spread the stays for this step.

Since I’m going to be using the inner washers on the final install, the width between the dropouts needs to be 140mm. I’ll have to widen the stays later. I’ll show how I do this in the next video. For now, I just want to get the hub motor installed to check for other clearances and centering as well as prepare the dropouts.

Check dropout for exact width of 10mm

The hub motor axle keyway is a full 10mm. Most bikes have dropouts to accommodate a 10mm axle but could measure slightly less because of paint. Some careful filing or sanding might be necessary to make the dropout width the full 10mm. The hub motor axle is going to need the full 10mm before it will slide into the dropouts.

My dropouts had a thick coat of paint which made the dropout width slightly less. I had to carefully file the paint off to get it to 10mm.

A general note about filing and sanding: Take it easy and take your time. It’s a lot easier to remove metal than it is to replace it. You can ruin your bike by removing too much metal or leaving jagged edges. Make sure to file a little, test fit, and then file a little more as needed. Make it smooth, clean looking, and precise. Large gaps will make the fit lose. Jagged edges are opportunities for cracks to form.

Next Step

The next video will cover dropout preparation, checking freewheel clearance, and centering between stays.

Hybrid Bike Vilano Diverse 3 Review

Summary Score: 8.2/10

The Vilano Diverse 3.0 Performance certainly represents a hybrid bike with a good blend of a road bike and mountain bike. It possibly leans more towards the mountain bike category with the shape and disc brakes but without suspension, you wouldn’t dream of using this for any serious mountain biking.

Hybrid Bike Vilano Diverse 3 Review


The price for the Vilano Diverse 3.0 Performance bike is great. Although most of the hybrid bikes we review come in with a high score in the price category, you can’t fault the fact that a hybrid bike in general costs a lot less than a road bike or mountain bike and as such, a huge cost saving for you for great commuting functionality.

Quality of the Components

The Vilano Diverse 3.0 Performance bike components can be broken down into various areas that determine the quality. Each of these components can in isolation drop the overall rating for a bike review, simply because the weakest part may be the area which causes the bike overall to be lower quality, i.e. a low-quality seat isn’t really an area for concern as opposed to low quality brakes or gears which make a bike unsafe or hard to use.

Frame: Simple aluminum frame with a fixed fork, no suspension

Seat: This is slightly less comfortable than other bikes reviewed but depending on how much padding you’d like, this will do a suitable job and allow you to ride at a decent speed if required without restricting leg movement.

Pedals: The standard pedals provided with the bike are very cheap, this would be one of the first items to replace.

Brakes: Disc brakes meaning you can stop in a hurry!! Always a good thing.

Gears: Shimano Tourney TX front & rear derailleur is definitely bottom of the range but still good enough for a commuter. The gear shifters are integrated with the brakes and readily accessible for gear changes for the 24 speeds (3 front,  8 rear).

Wheel set: Standard 700 wheel size similar to a road bike. Tyres supplied are Kenda who make great tyres so good plus there.

Weight: 26.2 pounds or 11.9 kilograms (reasonably light weight)Quality of the Components 7/10

East & Costs for Maintenance

If you use the bike a lot, you’re bound to need to do maintenance at some point. That might be as simple as fixing a flat tyre, adjusting the gears or changing brake pads.

The Vilano Diverse 3.0 Performance bike gets a good mark for ease and cost of maintenance. This is due to the fact that you’ll be able to do a lot of the work yourself. The wheels are easy to remove with quick release levers, the seat can easily be adjusted and with a bit of knowledge, you could even adjust the gears/shifters and disc brakes although I’d advise you take it to a bike shop for the disc brakes.

If any of the work is outside of your comfort zone, any bike shop will be able to do the maintenance for you due to the very common nature of the components and easy access to parts. Ease & Costs for Maintenance 9/10


The bike gets an ok rating for comfort. It’s more designed to be fast and simple as opposed to a laid back comfort machine. The main comfort issues are the seat and pedals. Both of these can easily be replaced if you’re looking for more comfort and I’d definitely be looking to replace the pedals very quickly.

One other factor to consider is the lack of fenders. If you bike to work in wet weather or on wet roads, you’re going to get a very wet backside. This is easily resolved with a low cost.


The Vilano Diverse 3.0 Performance bike is a nice looking bike. Although on the basic side overall for a look, it’s got a nice style for the more standard frame and where it’s positioned in the market. Again, this will be a personal preference issue where you need to decide if you want a more cruiser styled bike or not…

Home Improvement Case Study: Installing Air-conditioning in Perth

Things To Consider When Installing Air Conditioning System In Your Perth Home


An air conditioning system is an important investment in your home, especially during the summer. The heat humidity levels can sometimes be exceedingly high, which is why you need a good AC system. You need to install them properly too. The following are some great tips to help you successfully install the right AC system in your home. Remember that newer units are more energy efficient, more powerful, and quieter than the old models. So, you should settle for the newer models that offer more value.

Determine the size of the installation area

This is an important consideration since an oversized or undersized system will not be great for your home. This air conditioning size calculator is a great resource. It states that, generally, a bigger room will require a bigger AC system. On the other hand, smaller sized air conditioning units will be perfect for a smaller room.  An AC’s capacity is usually determined in tons (that’s the level of heat the AC system can dissipate). A 3-ton unit can expel about 36,000BTU while a one-ton unit gives out about 12,000BTU.

If you have a house measuring about 1,600 sq. f, it will take at least an AC system of 24,000BTU for better cooling. If you don’t have the technical knowledge about all these, an AC technician can help you out here. So, before you select a system, consult a technician to determine the right size of the unit that will be ideal for your home.

Installation requirement

You will most definitely need a new circuit breaker if you are installing the Ac in a house that’s never had any form of Ac unit installed. The circuit breaker will be installed in the electrical panel. You will also need a new mounting, new ductwork, as well as new wiring for the AC unit. It’s important to call a good professional to help you estimate all these.

Except you are an Ac technician yourself, it will be better to call a professional who will help to carry out correct estimate. It will be a waste of time and money if you decide to do everything on your own. When you get the setting wrong, you may need to spend more to put things back in order.

Select the right technician

You need to choose a good technician if you want the AC system to be installed the right way. Call a certified professional such as the guys from AirConWA who will help you estimate the requirements and advice you on the best AC unit to buy.
