Comparison: Stromer ST1 Platinum vs Currie Eflow Nitro

As we sell both the Stromer and the Currie Nitro Eflow bikes - bikes which share much in the way of looks and technology - we are often asked - "what's the difference between these two?"

The Stromer has long been our favorite e-bike on the market. Not a lot compares to the quality, speed and reliability of a Stromer. The Currie, however, comes close.

In our show room floor, though they are very different, customers often think they are the same bike, for a variety of visual reasons. Both feature the flag of the country in which they were designed: Switzerland. Both come in a deep monolith matte black color. Both are priced at $3999. Frame dimensions themselves are similar, featuring a hybrid/mountain bike geometry designed for comfortable commuting and recreation. 

The Stromer is flat out sexy. Not only that, it's fast and most of its technical features are better than the Currie. But there are some areas where the Currie excels and makes it a worthy bike to consider when buying an e-bike. 

Both have a 500W motor and a 36volt battery. The new Stromer, however, comes with a 14.5 amp battery that is also removable and charges faster than the Eflow. 

Both bikes come with larger cruiser-like tires, though they differ in size and tire tread. The Eflow bike comes with the popular MAXXIS Overdrive Excel hybrid e-bike tire. The Stromer ST1 Platinum now comes with Schwalbe Big Ben tires branded with the Stromer logo. The Maxxis tire is grippier and quicker and features the very bright light reflective side strip- great for night riding. Reviews of the Big Ben tires have been astounding though. They provide great grip, they are smooth, they are comfortable and they are very visually appealing with their giant cruiser looks. Goes great with the stealthy graphics of the Stromer.

In terms of performance, both the Stromer and the Currie use a 500W motor. The Stromer ST1 Platinum motor is "un corked" to put out a top speed of 28MPH. The Currie EFLOW top speed is 22MPH. Folks looking for a very fast production e-bike have been gravitating to the Stromer Platinum for that few extra umphs. 

Still, both bikes climb hills equally. On either bike, I find that, after a long day of work, climbing up a hill in throttle mod while pedaling to assist the motor and keep the speed, I'm faster on steep hills in throttle mode on the Eflow. On less steep hills the Stromer pulls away due to its miraculous top speed. 

Both also feature regenerative braking. Highly desirable and useful if you live and commute down or up a larger hill. 

What we tell our clients is that 20mph on a bicycle, with bicycle brakes, bicycle helmet, bicycle tires, bicycle frame and wheels- is faster than you think. 28mph is quite possibly faster than you need, if not potentially a little dangerous. 

Ebikes are great. They move faster than a bicycle in a bike lane, but they don't quite hold their own in a car lane. Cars misjudge your speed regularly. Whatever speed you find yourself needing- always remember that you are traveling faster than a bicycle is normally intended to go. 

For those who don't have the need for speed that the Stromer is capable of, a bike like the Eflow Nitro electric bike is fast enough. If you need to push the envelope- the Stromer Platinum could be for you. If you don't, the Eflow is an option, as is the Stromer ST1 Elite, which is $600 cheaper than the Eflow.

Where the Eflow does excel is in some of the bike's components, ergonomics and other features. The Eflow uses an FSA Omega Crankset, while the Stromer features an FSA Tempo.      

Pedals are important. The pedals on the Eflow are nice comfortable platform pedals that any commuter can enjoy. The Stromer comes with the less expensive track pedals that are tough on softer shoes. We recommend swapping them out for platforms.

The seat on the Stromer is quite stiff compared to the Eflow. This is another item we find that customers often have to upgrade during or soon after purchase on the Stromer. A nice gel seat goes a long way on a good commuter bike.  

Both bikes have good hydraulic brakes. The Stromer upgraded theirs to the Magura MT2. The Eflow uses the Tektro Auriga kit. The previous Stromer models had notoriously bad brakes. They squeaked constantly and their rotors warped. In an effort to keep the retail price down on most ebikes brake quality is kept at a minimum, generally speaking. Unfortunately, this doesn't account for the fact that most ebike riders buy an ebike to help them with hills and, as the saying goes, what goes up, must come down. But- when you are flying down your favorite hill and you're on a big heavy, fast ebike, believe me, you want good brakes. The new Stromer ST1 delivers with excellent Magura brakes, better than the Eflow with a radial pump. 

The two bikes use different types of controllers. The new Stromers put the controller on the right side and use a proprietary design. The EFLOW mounts its controller at the center of the bike and is larger in size. A nice feature of the Eflow is that it's removable. This is very useful if you have to flip the bike on its back to fix a tire in your garage, but it's also helpful when parking your bike in public. A simple twist and the controller is removed. 

The Standard version of the Stromer uses a rigid carbon front fork. It's super light and provides excellent road feel and handling. It is, however, stiff on such a heavy bike. You can get a suspension fork as an accessory that has a lock out too. The Eflow has a rigid fork with a mono shock built into it. Nice. 

For the 2013 model bikes, Stromer put out some accessory options called the City Kit, which comes in a few varieties. Great kits, a little on the pricey side, but they are integrated with the bike's frame and electronics, so your light system won't need a separate battery. This is ideal. One thing we don't much care fore is the proprietary rear rack design that requires the use of the fender set in the City Kit. A lot of customers have their own rear rack systems they want to use, or just don't like or need fenders, but for the rear Stromer rack you'll have to use the fender, unless you can jerry rig a forward mount for your rack. 

The Currie Eflow will take any regular aftermarket bike stuff. Good. 

2 big differences between these two bikes is how the battery is positioned and integrated into the frame. The EFLOW battery is right under the seat in the frame. With no rider on the bike, it gives a look of bulk on the bike, but that same postion makes the battery almost completely hidden by the riders legs when the bike is being ridden. The battery is removed by releasing a lock pin, pulling up on the seat and removing the battery like a cartridge. The battery on the Stromer is housed in the front down tube of the frame and removed with a locked and spring loaded door that opens up the frame. The Stromer is cleaner over all. The wide battery of the Eflow can actually catch the wind a little on its side. Not great.

In terms of ride- the Eflow Nitro seems to be a better ride for comfortable commuting. The Stromer ST1 geometry feels more speed oriented for easy sit-down pedaling, but it's stiffer. The Eflow is a good tall ride and with that seat and ergo bars adds to the bike's rideability.  

Our store is focused on experience, which is why we recommend a store visit where you can try out the various models and judge for your self, not some blogger. 

At the end of the day, right now the Cury Eflow is a main competitor to the Stromer in the United States if you want a well-made, fast, good looking e-bike with all the bells and whistles that will last. We highly recommend looking at both models before making a purchase decision. 

We keep both models in stock most days. See you at the shop.

Bosch is launching a new trail riding feature for Performance Line CX called eMTB mode. This new feature will automatically change between assistance modes depending on pedal pressure for optimal support on different types of terrain, allowing riders to concentrate their full attention on the trails and achieving #UphillFlow.

The eMTB mode replaces the traditional Sport mode (210% boost) with a “Variable” mode which provides assistance between Tour (120%) and Turbo (300%). This gives riders ideal power at all times, even at low pedaling frequencies, without them ever having to toggle between support levels. The amount of assistance is dependent on the rider’s pedal pressure (see above graphic), starting with light drive unit support at light pressure and increasing to maximum support as pedal pressure is increased. The system responds almost instantaneously and the rider continues to experience the “natural riding sensation,” whether starting off or accelerating. As soon as the pedal pressure decreases, the power assistance is smoothly regulated downwards. Thus the rider has much greater control when riding through narrow, winding sections of a trail.


eMTB mode will be available to old and new customers beginning in July

The iZip Dash Electric Bike Might Be Our Favorite Ebike Ever

The iZip E3 Dash from Currie Tech might be our favorite eBike ever. NOT ONLY does it look great, ride great, go 28 MPH and handle like butter, but at $2600 retail this bike is something you can bring home to the wife or husband and they won't look at you like you are insane because you just spent $6,000 on a bicycle. This is a bike that will take you long distances, quickly, doesn't make you look like a German design project from University and is backed by a great dealer network. 

The iZIP e3 Dash has nothing to hide. It has a style that any one can enjoy and that isn't afraid to show that it is an e-bike. It's unassuming design makes it really look like a regular bike even though its battery isn't hidden like other e-bikes. It says that it's not trying to hide its e-bike-ness. 

But, the most exciting thing about the DASH is its top speed. This e-bike cooks. We took the dash on a lunch run through heavy San Francisco traffic at noon time and we were able to cross town in just minutes. Once down on the Embarcadero we walked our bike into our favorite Salumi shop, grabbed a sandwich and headed back to the store to sell more ebikes. The getting around part was a blast. The DASH is light weight, has a predictable and usable suspension and its wide tires are great for San Francisco's crappy asphalt. 

At this feature set and top speed, the DASH is going to appeal to any one considering any of the higher end $4,000 ebikes such as the Stromer, eFlow, A2B and others. 



A Pair Of Ebikes For Him and For Her

If an ebike is on your horizon because you want to get more exercise, or not be bothered by traffic and parking, among the more stylish his and hers ebike combos we offer - we think - the BH Easymotion Neo Cross combined with the BH Neo Street ebike. Each bike fit the same needs of urban or suburban riding, or, take them on trail for light duty off pavement fun at the coast side or by the bay. These bikes will get you from your home in the lowlands of Atherton or Menlo Park, to the highlands of Woodside and beyond. 



Or, when the weekend is over, leave your car at home and hop on your bike. These are transportation devices that take you effortlessly and easily 20-30 miles at 20 mph. They are fun, healthy and inexpensive ways to get around. 

Charge it over night for pennies. Spend less time and money at the pump and our electric bikes will in fact pay for themselves in just a short few months. 

It's money in your pocket for better things. 

The two combined look well together. They match in power and style and look great in town going shopping or parked outside restaurant. 

BH Bikes are a Spanish bicycle company, one of Spains largest. The BH Easymotion line is their ebike line-up and known for their quality in components and design. Each bike uses a 300 watt motor with both pedal assist or power on demand (throttle) power.

Too Much Parking In Downtown San Mateo

Letter to San Mateo City Council members about planned increase in parking in downtown San Mateo.


Hello Mr Matthews and Mr Lim

I read about the recent parking meeting in the SM Daily Journal and wanted to contact you with my thoughts as a resident, father of 3, driver and cyclist. I think the idea of adding even more parking and more cars to the down town area is the opposite direction San Mateo needs to go. A city our size should be looking at reducing access to cars down town and bolstering it's walkability and rideability. 
We live in the Highlands, so visiting downtown usually, not always, involves a car drive. We also ride in by bike from time to time, during less peak times only, because it's unsafe otherwise. 
There is too much parking in downtown San Mateo already. There are too many cars in downtown San Mateo. Not enough pedestrian and bike friendly access. The sidewalks are narrow. Adding yet more parking to San Mateo isn't going to make the area more attractive for couples or families to linger and enjoy the downtown area. It will simply add more cars to the downtown area, making it even more unpleasant for people looking to do more than an in-and-out of one shop and go home. 
Less parking and more pedestrian space means a better sticky reason to stay in the area, rather than zoom in park and leave. There's already plenty of parking in the surrounding area of the downtown that goes empty during peak hours. 
San Mateo downtown is unsafe to walk around due to all these cars. It's also unbearably unsafe to ride a bike around unless you are an experienced commuter and an adult. During the evening I would never feel safe taking my family into town in the evening by bicycle to have dinner and see a movie and possibly do some shopping later and yet I would LOVE to do this and I know other families would also love to be able ride in to downtown and explore rather than have to get into a car, find a parking spot and so forth. 
And- there are actually cities who enable this and promote this. Let's follow their lead and get out of our 'car brains' for a bit. 
To become an actual destination where people will want to shop and linger, downtown needs a larger pedestrian area, more bike lanes and more out door activities. Look at what is going on in Redwood City and other towns where they've created a reason to actually get out of a car, shop and enjoy a downtown area. 
Instead of a downtown flooded by cars between 6 and 8, try to imagine a down town with families and couples streaming in by bicycles during these times, because they are want to really enjoy an evening. Let's see some bands playing out doors in the square in front of the theater. This is what I see in Redwood City around those times and on weekends. Let's promote and build that. 
We have great weather in San Mateo. Rather than pay nearly $4 million on 400 new parking places in the next ten years, put that towards building and promoting a walkable and rideable downtown. So what if we have to walk a little further to get to a restaurant or the movies. The end result is so much more healthy for people and the town itself.

Urban Arrow Electric Cargo Bike Makes It Easier Not To Own A Car

Wild, young, America is losing interest in the automobile. Once a symbol of speed and freedom, the car now signifies a nagging monthly payment, another thing to maintain, another mouth to feed, with gallons of expensive earth-polluting fuel each week. Traffic jams. Circling city blocks looking for parking or spot-hunting in giant soul-less parking lots and so on and so forth. 

The AAA says that it costs about $9000 per year just to operate/own a car in the United States. Young Americans don't want to be a slave to their cars, or the auto industry. They want effective, cheap transportation that's good for them, is low-impact and low-maintenance.  

Many wild, young Americans are looking at the cargo bike as a viable car replacement and the new Urban Arrow Cargo e-bike is one the most advanced example of its kind on the market. 

Imported direct from Amsterdam - the capital of bicycle transportation - the Urban Arrow is a joy to ride and to utilize. 

Considering that a car costs $9000 per year just to operate, using the UA as a car replacement pays for itself in just 6 months. 

Suburbanbikes / Motostrano is the California importer for these great bikes. 

Our first deliveries have been well received. 

The Urban Arrow cargo bike uses the famed BOSCH pedal assist mid-drive motor system to offer a smooth and powerful ride that takes the weight off starting the bike and climbing hills. 

This is a cargo bike of the highest order, well thought out and engineered as a real transportation and carrying solution, not a novelty. This is bike you can safely carry 3 small children to school with on a daily basis in good or bad weather. 

The Urban Arrow cargo bike takes a lot of the sting out of pushing a cargo bike around by pedal power. The electric assist makes it a little easier to get started and to climb hills. It also can extend the range of your cargo bike by getting you further, faster. In a place like San Francisco, for instance, you can easily get around the entire city with an Urban Arrow and never need a car. 

Mom's really like the idea of an electric cargo bike. You get exercise and fresh air. You get a safe vehicle to transport kids and go to the store. You get money savings and you get to park just about anywhere. Which makes the Urban Arrow a solution for progressive moms who want to do things a different way than lining up at the pre-school in a minivan. The Urban Arrow makes getting out an adventure and an exercise in exercising, as it were. 


The Urban Arrow cruises at speed around 16 MPH but we recommend keeping the speed down. Get there safely and calmly. As a bike, it's equipped with a front and rear light to keep you visible at night. 

There's a sturdy center stand meant to keep the bike upright whenever parked. 

The seat is a comfortable gel touring seat and it's a standard bike seat you can also swap it out with an even more comfortable. There are many accessories available for the bike.  

The Urban Arrow is in high demand. Right now there is a lead time of 5-10 weeks to get an order shipped. To find out more, contact our sales people.
