We build these wheels using 32 double butted spokes per wheel and DT swiss brass pro-lock nipples to keep your wheels true for many miles. Each wheel is precision built by professional wheelbuilders in our shop using high-tech spoke wrenches, wheel building stands, and spoke tension meters.

*Not all mountain bike trails are open to Electric Mountain Bikes. Be sure to check trail regulations before riding any single track trail.

There are many more factors to building a big and tall bike than most people understand. It is not as simple as just scaling up a “normal” sized frame and calling it good. When you do that, several things happen to the bike. First, the stretched out tubes become less stiff, which results in high speed frame shimmy. This is a scary by-product of a poorly designed bike. Second, the added material makes the bike heavier, especially if the builder tries to solve problem number one with just using bigger heavier tubes. Third, without a fork with a long enough steering tube, the handlebars will be far too low for the tall cyclist causing discomfort in the back, neck, wrists, and arms. Fourth, building a bike for a tall rider with average length cranks will make the rider feel like he’s pedaling a kids bike while sitting up very high. Lennard has developed great frame design concepts to address and solve all of these issues and more, which are all fully applied in the designs of Clydesdale Bikes. A Clydesdale bike designed by Lennard Zinn will be stiff and strong, while remaining lightweight. It will never shimmy at high speeds, and all of the components, including cranks and handlebars, will be proportional to the rider. Fit, performance, comfort, and durability will all be superior on a Lennard Zinn designed bike than a big and tall bike from any other designer out there. We guarantee it.

Are you wondering why the team at Clydesdale Bikes always recommends titanium for the bike’s frame? It’s because it has so many benefits over utilizing more traditional materials like aluminum, steel, or carbon fiber. Did you know that in addition to being half the weight of steel, titanium also has a ton of fatigue resistance and strength that allows us to avoid building bikes with oversized tubing? Even with smaller tubing, you can still expect an extremely compliant ride with minimal interference from rough surfaces, small bumps, and road buzz.

Along with your comfort during any type of ride, titanium also ensures the longevity of your bike. Whether you have a gravel ride or an ebike, titanium is a material that guarantees your bike stays corrosion-free. Without having to worry about rust eating away at your frame, you have the flexibility to paint your bike or leave it bare. Never worry about scratches on the exterior of your bike again! Even better, no corrosion within the tubes also provides a better option for internal cable routing.

Choose titanium and discover a material that flexes more without damage, never suffers from notch or crash damage that may lead to catastrophic failure, and won’t degrade when exposed to UV rays. With titanium construction, a bike from the Clydesdale team could last you for the rest of your life – if not longer!

Titanium for Extra Strength

Pretty much every custom bike we make is designed with a titanium frame. Even the best EMTB can use the benefits of this material. Half the weight of steel with enough fatigue resistance and more than enough strength, titanium frames allow you to enjoy a sleek ride with amazing compliance and minimal road buzz. We can make our tubing as large as we want without adding too much weight to your ride!

Titanium also has the ability to flex much further than either aluminum or steel without experiencing permanent damage. It even outdoes carbon fiber, which is vulnerable to notch damage and crashing, as well as an epoxy matrix that will degrade after years of UV light exposure. Our titanium bike frames can literally last you for the rest of your life!

We also prefer titanium for our ebikes for tall riders because this material never corrodes. We can paint it in custom colors or plate it to minimize scratches. Our team also routes the cabling internally, so that it’s protected by the titanium casing from rust and corrosion.
