    Brompton Tire Guide

    Looking for some new rubber for your Brompton? We have been riding and selling Brompton Bikes for over 10 years. Finding the right balance between durability, ride quality and efficiency will depend on where you ride, how you ride and what your expectations are.

    • We find the Schwalbe Marathon to be a shop favorite (not just for Bromptons, but overall) because it has mega durability yet the Marathon is quite speedy. The downside is that it is a fairly stiff tire, so the ride isn't quite as smooth as some other options.

    • If you want to be protected from flats as best possible, the Marathon Plus is the way to go. In Minneapolis it might be considered overkill, but if you're in a cactus state it might be necessary. This is the highest mileage and best flat protection offered from an air filled tire.

    • The Marathon Racer is Brompton's default stock tire. The Racer is a nice compromise between durability, smooth ride and speed. You're not going to get the same mileage as the Marathon and the flat protection isn't quite as high, but you gain a more supple tire which translates to a smoother, speedier ride.

    • If you like kicking it old school and want the narrowest and highest pressure tire, then the Kojak is for you. This has been the go-to for Brompton racers since the day it was introduced. While the folding and the non-folding Kojak look identical, the folding Kojak is lighter and more supple (higher sidewall chord count).

    • The Schwalbe One is the newest performance minded tire in the lineup. We LOVE it. Fast, lightweight, supple, durable and even a bit chubby. The only downside is the price, but hey, we don't need to replace our Brompton tires very often, so it is money well spent.

    • While the Marathon Winter is only going to appeal to those riding on rather extreme conditions (like those of us in Minnesota), it is a great tire for icey conditions. The Fin's made this tire possible and Minnesotans thank them ; )

    Schwalbe Marathon HS 420

    SIZE: 16 x 1.35"

    ETRTO: 35-349

    PRESSURE: 65-110 psi

    WEIGHT: 420g

    BEAD: Wire

    COLOR: Black

    COMPOUND: Endurance

    If we had one tire to recommend for the utility rider or daily commuter, the Schwalbe Marathon HS 420 is it. It is a little slower rolling than others on this list (except the Marathon Plus), but in exchange it will reliably shrug off glass, wire and other debris. We find this this is a dependable tire that will provide favorable riding characteristics.

    Schwalbe Marathon Plus HS 440

    SIZE: 16 x 1.35"

    ETRTO: 35-349

    PRESSURE: 65-110 psi

    WEIGHT: 480g

    BEAD: Wire

    COLOR: Black

    COMPOUND: SmartGuard

    The Schwalbe Marathon Plus HS 440 is Schwalbe's best selling tire and is also the most puncture resistant tire available for Brompton Bikes. It is an extremely durable, long-wearing and flat resistant tire. This is the highest mileage and most flat resistant tire available for Bromptons.

    Schwalbe Marathon Racer HS 429

    SIZE: 16 x 1-1/3"

    ETRTO: 35-349

    PRESSURE: 65-110 psi

    WEIGHT: 282g

    BEAD: Wire

    COLOR: Black

    COMPOUND: SpeedGrip

    The Schwalbe Marathon Racer HS 429 is the best-of-all-worlds option for your Brompton, and is the standard tire option on their bikes since 2017. We find that the Schwalbe Marathon Racer provides excellent city / commuting performance, while still being reliable and rugged enough for everyday use.

    Schwalbe Winter HS 396

    SIZE: 16 x 1.20"

    ETRTO: 30-349

    PRESSURE: 65-115 psi

    WEIGHT: 460g

    BEAD: Wire

    COLOR: Black

    COMPOUND: Winter

    The Schwalbe Winter HS 396 is the best way to winterize your Brompton. This tire provides outstanding grip on ice, and the winter compound provides reliable stability in winter conditions. We also like the added puncture protection and reflective sidewalls.

    Schwalbe Kojak HS 385

    SIZE: 16 x 1-1/4"

    ETRTO: 32-349

    PRESSURE: 70-115 psi

    WEIGHT: 230g

    BEAD: Wire

    COLOR: Black

    COMPOUND: SpeedGrip; 50TPI

    The Schwalbe Kojak HS 385 is a high performance Street Slick, well suited for use on the road. We find that the Kojak is ideal for city / urban performance riding due to its high on-road grip, low rolling resistance, and puncture protection. Reflective labeling is just the icing on the cake.

    Schwalbe Folding Kojak HS 385

    SIZE: 16 x 1-1/4"

    ETRTO: 32-349

    PRESSURE: 70-115 psi

    WEIGHT: 175g

    BEAD: Kevlar

    COLOR: Black; RFX

    COMPOUND: SpeedGrip; 67TPI

    The Schwalbe Folding Kojak HS 385 has similarities to the non-folding Kojak, but it's lighter weight, has a kevlar (folding) bead, higher threads per inch, and a full reflective strip. The higher thread count makes for a lighter and more supple casing. Additionally, the compact fold makes this a great option if you need to pack an extra tire.

    Schwalbe ONE HS462A

    SIZE: 16 x 1-1/3"

    ETRTO: 35-349

    PRESSURE: 65-100 psi

    WEIGHT: 180g

    BEAD: Folding

    COLOR: Black w/ Tan Walls

    COMPOUND: Addix Race

    The Schwalbe One HS462A is the fastest and lightest Schwalbe tire available for the Brompton. Here at Perennial Cycle, we prefer the slightly wider Schwalbe One VS. the Kojak, as we find the the ONE gives a slightly smoother ride and gives a bit more durability. If you are looking for the speediest tire option, this might be 'the one'.

    Schwalbe Tubes

    Schwalbe tubes have extremely high air retention and elasticity. We recommend Schwalbe Tubes for all of these tires.

    The Schwalbe AV4 is standard (shrader valve) for Brompton Wheels. This tube is used unless you have non-standard rims.

    WEIGHT: 85 grams

    STEM LENGTH: 40mm

    VALVE TYPE: Schrader Valve

    The Schwalbe SV4 is used on non-standard (presta valve) Brompton Wheels. This is used if your rims are setup for presta valve tubes.

    WEIGHT: 85 grams

    STEM LENGTH: 40mm

    VALVE: Presta Valve

    Dynamo Lighting + Perennial Cycle

    Perennial Cycle sells more dynamo hubs, lights, chargers, wiring kits, wheels, connectors, mounts and all other things related to dynamo lighting than any other bike shop in the US!

    Busch & Müller Luxos U

    The reason is very simple: we absolutely love and believe in dynamo lighting as a true game changer when it comes to seeing and being seen on the roads. No wondering if you have them in your bag or if the batteries are charged or if you remembered to remove them from your bike the last time you used them. You can be confident that your lights are working.
    If you are unfamiliar with what dynamo lighting is, check out our blogpost about it HERE.

    This is my DaMN setup. DaMN is an event that starts at midnight (and it's dark at midnight)

    Most of our dynamo customers are commuters, touring cyclists, bike campers, randonneurs and the big mileage gravel racers.
    Commuters are all about the lights, cycling tourists are most interested in getting setup to charge their phone and less concerned about the lights and the big mileage rando and gravel riders are in need of both the charging and the lighting.

    -

    The dynamo wheels on our website have options (options show up after choosing your color) for both front and rear lights (and in some cases special wire kits) that make it possible for you to see exactly what the cost would be to setup a complete dynamo kit with a front and rear light. This can be a great tool if you are new to dynamo and need the full kit or if you're simply trying to work out budget.
    We used to start off with a wheel and front light, but the reality is, dynamo rear lights are inexpensive and the wiring is not problematic, so it's best to just go for it!

    -

    Brompton folding bikes are ideal candidates for dynamo lighting. These bikes are very utilitarian and thus end up being ridden at night with regularity. Brompton understand this and offers a dynamo kit that is a great price, though lacking in brightness. Lots of people get custom kits or have us upgrade their current lights. We have tons of experience setting up all bikes with dynamo lighting kits. Also we work hard to keep a great selection of dynamo parts and accessories in stock.

    -

    Why so German?
    Our dynamo hubs and lights are almost exclusively from German companies because Germany has a lot of cyclists and very strict laws regarding riding a bike at night (as in you can't ride at night if you don't have self generated lights).
    Because of these rules, there is a much stronger market in Germany, so naturally their dynamo companies rule the world market. We consider ourselves lucky in regards to this German dynamo monopoly. Busch & Müller and SON Nabendynamo are developing absolutely phenomenal product.

    -

    Dynamo hubs can be used to charge devices. In this picture you can see that I use a SON Deluxe front hub and The Plug III to change my phone that is tucked inside the Banjo Brothers Frame Bag.
    We have a blogpost dedicated to using dynamo hub power to charge devices as it can be a challenging to get a good understanding. Check out that Blogpost HERE.

    -

    This is our dynamo demo bike built by a past employee that built amazing bikes in the basement (thanks Matt!). The hub is a SON Deluxe that Matt fit a singlespeed freewheel onto (using disc brake rotor mounts).
    Sometimes we use it to troubleshoot issues, but mostly it's used to show how little resistance there is when you are using dynamo hubs. Our dynamo demonstrator allows you to spin the wheel with the lights off, and then with lights on, making it very easy to compare. Each front light has a different rear light connected to it.
    Currently the front lights on the demo bike are the Schmidt Edelux, Busch & Müller IQ-X, Lumotec IQ Cyo T Senso Plus Premium and IQ Lumotec Avy N Plus.
    The rear lights are the Busch & Müller Toplight Line Small, Secula Plus (fender and chainstay mount), Toplight Line Plus.

    Introducing The Flat S Senso Light

     
    Here at Perennial Cycle we love the German Busch & Müller dynamo and battery-operated lights! Germany has strict cycle lighting laws and B&M abide by them and we benefit from that. We have recently brought their battery powered Flat S Senso light into our shop and have found it to be a wonderful upgrade to a Brompton.
     
    The Flat S Senso has both a light and a reflector, so it is legal to use this to replace a reflector on a bike. The Flat S Senso sports B&M’s LineTec technology which has a single LED as well as multiple mirrors that extend across the light in a  line, making you very visible on the road. In its Senso mode (S), the light turns on and off using light and  motion! This means that it will turn on whenever the bike is in motion and it is dark out  and it will remain on for a couple of minutes at a stop to keep you visible. If no further motion is detected the light will turn off on its own! The light works on both rack (R) and non-rack models (L/E) of the Brompton. When installing it on a L/E (non-rack or non-fender) all you need to do is replace the reflector with the Flat S Senso. The reflector/light mounts on the the bike have a slotted hole that allows the light or reflector to slide up or down a bit. When tightening the Flat S light on, be sure and have the light as low in the slots as possible. This allows clearance with the ground when folding the bike.This light also fits very nicely on our Tubus and Racktime racks (also German engineering at is finest).

    Cateye Rapid Mini - 😻 Light up the Night

    cateye rapid mini

    We have many lights
     to choose from at Perennial Cycle as we like the idea of being seen on the road. When it comes to keeping it light and simple, the Cateye Rapid Mini has you covered. We have brighter and/or longer running lights available, but this current shop favorite is simple and minimalistic. At just 2 inches in length and 3/4 inches wide it is easy to throw in a pocket when locking your bike up.

       

    The Standard Rapid Mini comes with a tool-free seatpost mount and a USB charging chord.
    The Brompton specific Rapid Mini comes with a Brompton saddle mounting bracket.
    Late in 2016 Brompton Bikes started coming with a slight modification to their saddles. On the underside of the saddle they made a mount that is there specifically to fit a little bracket for the Cateye Rapid Mini light.



    Brompton Specific Rapid Mini                 Standard Cateye Rapid Mini

     

    Cateye also makes a separate saddle rail mount that is compatible with the Rapid Mini, so you can easily switch your light from bike to bike.
