I took delivery of my 2015/16 base Turbo in mid-November of 2015 at a price of $3,000 (Note from its original price of $3,800 has now dropped to $2,500). Today I turned 1100 miles. I put these miles on in Nov-Dec of 2015 and then in March-April, June, some of July and most of August of 2016. In 9 1/2 months, I have lost 4 months of riding time due to weather, travel, and medical procedures, but have thoroughly enjoyed riding my Turbo for exercise, companionship (with my daughter), and personal pleasure and recreation. Though outfitted so it could be a commuter bike, I am retired so do not use this bike as a daily commuter.
Some thoughts about my experience:
As it stands now, this is really a "near-perfect" e-bike for me. The last change I am contemplating is purchasing a Turbo S 691Wh battery. This would not change performance (which is already just fine for me), but would increase my "full throttle" range to 35 miles, high speed cruise (ECO 60-70) to 50 miles, and my long distance cruise (ECO 40) to 70+ miles. Further, I would hope that between the two batteries (original 468Wh and a second 691Wh), I could increase the useful life of the bike to nearer 10,000 miles.
Some thoughts about my experience:
- Range: I am comfortable with rides up to 25 miles without worrying about battery management at all. Above 25 miles, I need to avoid use of TURBO. Beyond 35 miles, I need to be very judicious about use of TURBO or ECO70. I believe I can stretch to 50-55 miles (though 45 is as far as I have gone so far) if I am rigorous about staying at ECO40.
- Speed: Full TURBO mode allows me to average above 20 miles per hour (as high as 22 on a couple of rides), but the base TURBO is not as fast as a Stromer ST2 or Turbo S. On the other hand, when riding with my daughter (on her unassisted carbon fiber road bike), I really do not need more than ECO40 to average 15-17 mph. If I want to "cruise" along with her and keep my heart-rate down, I can up that to ECO50.
- Power: The 200W nominal Go SwissDrive motor in the base Turbo is not a powerhouse, but still is satisfying and allows me to do a pretty good job. For the riding I do and for my own goals (keeping up with younger unassisted riders over longer distances), it is just about perfect. My 65 year old body and legs provides around 50W - 150W over distance while the bike contributes anywhere from around 80W-200W.
- Gearing: This is something that needs work. The stock rear cluster of 11-32 is not low enough for serious hill climbing and has too many "high" gears given my weight, age, and the motor power of this bike (see above). The SRAM 11-36 cluster should have been the stock cassette provided by Specialized as it is on the 2016 Turbo X. My recent upgrade to an 11-speed Shimano XT with 11-42 cassette provides a 24% lower 1st gear without giving up anything on the upper end. I now can climb just about any hill while maintaining an aerobic pace. I can cruise at the maximum assisted speed of 42 kph (26.1 mph) in my optimal cadence range and I still have a higher "descent" gear good for up to around 33-35 mph.
- Comfort: I find the stock seat and bar position pretty good for me. I have changed over to a Thudbuster ST seat post, switched to a shorter 620 mm carbon fiber handlebar, and replaced the stock grips (not good for me) with ERGON GP5's. I also use Shimano SPD pedals and riding shoes. I find that I can ride 20 mile stretches fairly comfortably before I need to take a rest due to numbness.
- Modifications (see pics below):In addition to gearing changes and ride comfort changes noted above, I have upgraded the braking (Kool-Stop pads), added the fender/rack kit from Specialized, purchased a rack bag, swapped out the 700 x 45c tires for lower rolling resistance 700 x 35C treaded Michelins, and added a Garmin 1000 computer with Bontrager Trip 3 backup. I also experimented with a 44T front chainring and bar-end Winglight turn signals, both of which I am not currently using.
As it stands now, this is really a "near-perfect" e-bike for me. The last change I am contemplating is purchasing a Turbo S 691Wh battery. This would not change performance (which is already just fine for me), but would increase my "full throttle" range to 35 miles, high speed cruise (ECO 60-70) to 50 miles, and my long distance cruise (ECO 40) to 70+ miles.
