Services For Custom Made Electric
Downhill Mountain Bikes

David Flather and Pinnacle Innovations have over 40 years of experience in custom fabricating and machining all types of metals including the commonly used 6061 aircraft aluminum that we use for machining new electric downhill mountain bike parts. In addition, I have over 35 years of spraying automotive and industrial paints - with some 30+ complete car paint jobs, several boats and countless bike frames under my belt.

We will give you exactly what you want:

  • Custom machining of rear suspension linkage plates to give you more travel, multiple adjustments and add bearings if none existed. See some machining pics down the page...

  • Custom machining of DH bike stems

  • Custom machining of custom chain tensioners

  • Custom painting of bike frames, forks and rims. I prefer to use the super durable Endura line of industrial aircraft polyurethane paint as it is not only cost effective but we can mix any colour under the sun. A variety of metallics are also available. If you want a super high gloss, we can also spray a second layer of Endura Kappa Clearcoat which we can then carefully sand to 5,000 grit and polish. Before painting, I will completely disassemble your mountain bike. I guarantee you a perfect finish everytime!

    In most cases I will recommend we use Endura polyurethane aircraft paint as it is by far the most scratch resistant paint available, we can match any colour that you bring us and it happens to be one of the most cost effective paints available. We can also spray other top quality finishes such as Glasurit automotive paint, BASF automotive paint and DuPont automotive paint. Custom metallics can also be chosen. See the photo below of my 26 year old Endura paint job on my yellow 1999 Norco VPS long travel cross-country bike with over 55,000 km on the original paint - it still looks great!

    Worth noting is that roughly 90% of the time spent on custom painting is all in the surface preparation with sanding to 400 or 500 grit, filling any deficiencies, masking and removing all of the wax and grease. The actual spray time is only about 10% of the work and I use a variety of sized automotive spray guns - some valued at over $1,700.

    People often ask me why I paint my bikes in such bright colours? Well, the answer is simple, the bright colours make up for my dull personality (laughs). Actually, I have found by chance there can be benefits from custom paint and bright colours that can include:
    1. Far greater visibilty if you are ever riding in traffic.
    2. Anti-theft. Yes - it is true. My bikes have become pretty recognizable in the North Shore Community diue to their customization and bright paint jobs and back in 2005 I actually had a breakin at my home shop where my 1999 Norco VPS was stolen from my locked and secured garage/ machine shop. Below is a pic of this bike (which has the original paint job on it that now has over 55,000 km of all types of riding on it without any noticeable paint wear) that as you can see is custom painted bright yellow and also has my name in vinyl letters on it. I actually got a phone call before I even knew the bike was missing from my West 20th St. address asking if I was missing a bike. I quickly went and discovered to my horror that I was. It turns out a neighbour from across a small river and park had found the bike off the side of a trail when walking their dog in a nearby park trail, saw the name and website address on it and called me. I was then able to go over to their house and pick up my missing bike.

    I suppose that the thief soon realized that he would never be able to fence such a custom bike and simply ditched it. He did however make off with a standard/ non custom mountain bike and some of my tools which were never recovered.
    3. Your mountain bike is an important part of your life and should also reflect your personality. So why not customize it to suit your style?

  • Custom installation of electric bike conversion kits. We can provide a variety of kits including mid-mounted Bafang geared kits as well as rear hub motor kits. Direct drive kits tend last about twice as long as geared electric motor kits but also weigh close to twice as much. About the minimum level of power that I would recommend is 350 Watts and the maximum is about 750 to 1,000 Watts. This will provide most riders the ability to climb any mountain and still keep the battery size/ weight and overall cost reasonable. Generally, we use 51 Volt or higher systems and we can offer a variety of controls and displays - as well as a battery charger.

    Generally, 750 Watts is about the maximum power level that is "Street Legal" which is the case here in BC. Also, the speed must be limited to 32km/h whether pedalling or not on flat ground with the power turned On.

  • Custom decals for many brands of forks, rims and frames. If we repaint your parts why not put a fresh set of decals on them?

  • Custom airbrush graphics. If you want to go that extra step I can always contract out custom airbrush work for you and then we can clear coat over this.

Everthing that I do is done in-house with the exception of anodizing or chrome plating of polished aluminum parts, any TIG welding that may be required (although I do have the capability to simple aluminum welding now and plan to add a TIG welder to my toolkit) and wheelbuilds - which often require the creation of custom made spoke lengths for specialty hub motors as well as the Rohloff hubs. Equipment in my shop includes:

  • Heavy duty vertical milling machine
  • 5hp 80 gallon air compressor
  • Band saws
  • Gear reduction cold cut metal saw
  • Drill press
  • MIG welder with spool gun for welding steel and aluminum
  • Professional automotive spray guns
  • Just about any hand and air tool that you can imagine!
Some of the motor and hub systems that I offer:
Bafang mid mounted ebike geared motor kits
GrinTech All axle direct drive rear mountain bike electric hubs that fit a variety of axle sizes and axle spacing
Rohloff Speedhubs - disc brake compatible 14 speed internal transmission hubs made in Germany
Bafang mid mounted ebike geared motor kits.

GrinTech All axle direct drive rear mountain bike electric hubs that fit a variety of axle sizes and axle spacing.

These are made in Canada and wherever possible we try to steer Clients to products made in Canada, the USA or Mexico and away from Chinese made products.

Rohloff Speedhubs - disc brake compatible 14 speed internal transmission hubs made in Germany.

Important Notes:

1. Please note that not all mountain bike frame manufacturers will support the frame warranty with an electric motor conversion kit installed. This predominantly refers to lighter and some all mountain mountain bikes as well as some older frame models. The reason is simple: not all frames were designed to handle the extra torque that motors of say 500 Watts and higher can exert on the frame. It is the responsibility of our Customers to ensure that the mountain bike they bring me for conversion is suitable for an electric motor upgrade.

2. Please not that we prefer to use North American made parts for quality and safety assurances and recommend recharing all ebike batteries outside of your home in a safe and dry place.

Custom machining video coming soon...

Below are just a few pics showcasing some of the custom electric downhill mountain bike machining, design and custom paint services work that we do:

Pinnacle Innovations' custom made rear suspension linkage plates - made from 6061 aircraft aluminum that permit super long rear wheel travel and fully equipped with bearings on all pivots and custom anodized lime green
Pinnacle Innovations' custom made high rise double clamp bar stem - made from 6061 aircraft aluminum and custom anodized blue
We offer not only custom paint in any colour you can imagine but also custom replacement decals for things like Fox forks

Custom made 6061 aircraft aluminum rear suspension linkage plates with full set of bearings and three or four head angle and travel adjustable positions with quick release shock bolt.

Shown are two sets - one set is for DH Dave's yellow electric pedal assist downhill mountain bike and the other, shorter set is for DH Dave's green non-electric downhill mountain bike.

We offer not only custom paint in any colour you can imagine but also custom replacement decals for things like Fox forks

In most cases I will recommend we use Endura polyurethane aircraft paint as it is by far the most scratch resistant paint available, we can match any colour that you bring us and it happens to be one of the most cost effective paints available.
