These Serfas tires work as good as they look—as do the brake pads.

I’ve been riding this project E-bike for a many weeks now. It came together nicely and much of what I like about it are the small details. A bunch of those details have the name Serfas on them. This isn’t the first time Serfas have been involved in one of my projects, yet this time they have outdone themselves. Although the pieces may not stand out to the casual observer, they all work together to make the biggest of differences.

The product line at Serfas is wide ranged, and I think you will see a little of this as I outline each of the parts that help make this ULTIMATE COMMUTER E-BIKE BUILD so comfortable and reliable. If you decide to build your own version of what you consider the ULTIMATE, using any or all of the Serfas items I have been able to incorporate in my project would be quite smart indeed. Let’s see what we have, starting at the front

#262   Serfas   Headlight

The headlamp is in white and the battery in gold.

One of the reasons I got the base bike for so little were the cracked sidewalls on the tires, so replacing them was a given. A shiny new pair of Serfas Vida Survivor tires stood out in their catalog, yet now really shine once mounted up on the rims. I wanted a good ride and a near zero chance of flats, and that is exactly what I got. In the 700 X C size, they have a little bigger cross section to help get away from the super skinny rough riders. These Vida tires claim a low rolling resistance and a long tread life, one I look forward to and the other I can feel already.


Serfas has a wide variety of tires (of all types and sizes) and offer tubes to match. They too have thorn-resistant tubes, yet not in this size so I had to source my own. I backed those up with Slime sealant, figuring this narrows my chance of flats to near zero, barring some massive nails and screws. Another byproduct I enjoy with this combo is that the pressure in the tires stays up way longer than the thin standard tubes. The Serfas brake pads I installed are strong and smooth. On a bike like this you want to be able to stop when needed, so Serfas tires and brake pads are making a big difference.

Other than the LightMeUp Safety Lights that adorn the rims, Serfas has covered all my lighting needs beyond belief. My wife won the Limited Edition TSL-2500 Serfas light through a Facebook contest. It turns out it is incredibly bright, has a massive battery (with a USB port) and a remote switch for the handlebar. I got them (Serfas) to add the wired taillight (TL-80), so my full lighting is supported by the one battery. It is very easy to see and sets its modes to match which of the 4 power levels the headlamp is set to.

On board the bike I carry a Serfas TSl-500 headlamp and USL-TL80 taillight for back-up lighting if needed. The both recharge with a USB cable, work great, and are lightweight to have in my panniers for emergencies. Also in my panniers are a pair of Serfas bike locks. I actually have 3 to cover different situations. The Double Espresso is used to secure my Serfas RX saddle and Body Float seat post. For all out security the 12 lbs. Big City Chain & U-lock are more secure than most any thief can bypass. For less weight and more secure parking settings, I use the Serfas CL-15 (15 mm cable) Combo lock that is plenty strong too.

This RX is one of the best saddles I have ridden. In this shot you can see the big Serfas saddlebag and the wired (to the headlamp battery) rear taillight.


In the comfort department my cotton shorts hit the Lyrca on one of their new RX-921L saddles. I have a couple of the Serfas Tailbones saddles on some of our other bikes and I think they are dreamy. It turns out the RX is total heaven. With some cool flexing and just the right amount of cush (and width), this platform is perfect. Finding the right saddle can be tough and that is why Serfas offers a big selection (like most all their products), yet take it from me, this bike seat is my idea of perfection.

Like saddles, I have some of their ergo grips on other bikes. For this project I needed some narrow ones to make room for plenty of other things on the bars so I chose the (GS-SWGBG) Twist-Shift Connector ergo grips, a choice I am fully happy with. I needed a frame and saddle bag too, and Serfas was happy to comply. The frame (stem) bag has magnetic clasps and holds my headlamp and lamp battery perfectly. Velco straps hold it to the frame and make it easy to remove when parked and locked.

With so much on the handlebars (including the left side twist throttle) these grips fit and work just right.

My saddle bag is pumped full of items needed for the open road (more on that in future posts in this series). It is their BS-1D model that comes with a tire pump, mini-tool, and a patch kit with tire levers. A few of those items reside in my panniers, yet so much more is packed into this spacious bag. I asked for their much more useful ST-SL mini-tool to make sure I can cover minor repairs for my friends and I when out riding.

Maybe this all reads like an advertisement, and in some ways it is. Serfas was generous to supply all these products to help make my “ULTIMATE” project E-bike just that. Yet if you follow along at all with my writings and reviews you know I wouldn’t spout so strongly without total satisfaction with the the pieces I review. Not just one Serfas accessory made this work, it was the sum of them all that lifted this bike to new heights.

Extra lights and other items tuck into my panniers. Many misc items fit into the saddle bag.

If I were asked to choose my favorite part it would be hard. Where my body touches the bike at the RX saddle and ergo grips would be easy to pick. Still, where the rubber (of those Vida Tires) hits the road I am constantly amazed at the performance levels at each twist in the road. In many ways I didn’t need all these things, but I am so glad the ULTIMATE COMMUTER E-BIKE BUILD has each and every one of them.

An upcoming article in this series will outline how I met each of the goals I originally set for this project and myself. Even though this pursuit is about an E-bike and commuting on it, it is also about making it just right in many ways. Serfas has fulfilled it though the bits and pieces from the most important tothe least significant. Each is a champion doing exactly what it is intended to do.

Although heavy to transport, the Big City lock seems massive.

    Hi TurboBob! I want an ebike and have been researching them for months. I want to replace my car for most commuting and errands, to get more exercise, to have more fun, and to reduce impact on the environment. I have a little boy I need to carry/tow around, and I live at the top of a big hill in Irvine/NB area. None of the ready-made ebikes have fully appealed to me (so big and heavy!), except the Faraday Porteur, but I fear that it would be underpowered for towing my groceries and little boy uphill. My husband rides a racing bike for recreation, does all his own maintenance and repairs, and wants to do a conversion for me. It does seem like I can get a lot more power and range for my money with a conversion, and still have a relatively lightweight bike. We’ve taken the first step by buying a used Jamis Coda Sport steel-frame bike for me. It’s old (2005) but in good shape with superior components (Shimano Deore) compared to current model. Now we are trying to decide what motor. I’m leaning toward the Bafang BBSO2 mid-drive 750 watt, which sounds great except I’m nervous about shifting properly. I’m doing OK shifting through terrain changes, but I need to remember to downshift before stopping at lights. We do have neighbors with Pedegos who carry their toddler and some bags of groceries, have gone to PCH and back, and seem to have no problem with the power of their rear-hub Pedegos. What do you think?

    • That sounds great, as E-bikes are so much fun and make so much sense.
      Yes, a mid-drive isn’t for everyone. The need for correct and timely shifting is part of the issue. Still, if you use the power mildly when you first start out, having it in an upper gear isn’t too bad.
      A strong hub motor is most likely best for you. With your extra cargo and hills, make sure to get a geared one—not a direct drive,
      Either way, if it is a good kit and installed well—you should love it.
      Make sure to let us know how it works for you—and maybe a photo or two. My Facebook page is a great place to share photos of your new E-bike.
      Thanks for writing.
