A real Mtn biker with real Mtn bike tastes. The demands of the trail are real and forth telling. A cheap trail or mtn bike will not perform or last. Same thing applies to MTN ebikes. The extra weight demands higher end and rugged components. For 2-3 lbs, sacrificing weight for strength is...

The bike is not for everyone. The 14 Rohloff gearing makes it more efficient than a hub motor on and off road especially, but one has to go through the gears. - tradeoff of ease and convenience for efficiency. If I could afford it, it would be a great high speed commute option to get me to...

RoadW, There is nuance here. The bike has 5 levels of assist. Select the lowest level and the rider will have less assist than several bike on this forum. Did it become a bicycle again, ass of a sudden? Second, if the bike was PAS only, and only has top assist of 1500W, and no throttle, is...

Classification doesn't make it less of a bicycle. Many bikes ride 30-35mph with ample safety, good brakes, stability. If the gears are high enough and one is still pedaling to add power... It's a bike to me. Being this is a High Speed Thread on an Electric Bike forum, all 28mph+, non-...

You are right... per the un-official ebike laws and propaganda of classifications, the power limit is 1hp, 750W... I forgot that detail.

2017 : A new year of ebike commuting.... let the Son shine in, face life with a grin, get on your bike, share the love.

Typo, sorry about that. Bosch speed bikes have 60nm or torque and 350W ave power, likely 500-700W peak however. The Opti 15R has 175nm of torque and 1500W ave power, maybe more for peak. That will accelerate much faster. To maintain 28mph requires the full 350W Bosch output, leg power, a...

f it had PAS and a limited speed at 28mph, it would qualify like all the Bosche speed mid- drives. But it would accelerate much faster. 175 vs 60 nm of torque, and 1500 vs 350w of power.

I keep up with the latest offering from Optibike, since I owned a couple of them from 2007-2012. These bikes are the cat's meow, but pricey. The original FULL suspension (All FOX), high speed (+28MPH), large battery (1000 Whr, full hydraulic disk brakes, integrate front head light, and high...

C Court, I echo those spec requirements for commuting, as did EM rider. I have 8 years of commuting experience. Being able to hit 28-30 with assist and hold it via motor wattage + pedaling is nice to have. Likewise, typical 25mph seems to be a safe, but efficient speed against wind without...

Great insights.

Great Pic, bike and chick!

I did a 48V battery upgrade and it didn't help the thermal cutback issue. If anything, it cut back sooner because it delivered more power and heated up faster. The Falco units are PROGRAMMABLE. They can be set to 20mph, 28mph, or unlimited, maybe, if the firmware/software has that option. You...

Great story and relevant! Thanks.

Nice reply. I went mtn biking with an old friend last week. Both of us about 50 yrs old. He is out of shape and we did a lot of resting and he knows how to mtn bike. I kept thinking, "if only I had a mtn ebike, pas." It would have been a really fun hour ride. Ebikes allow the older and...

That is a sweet looking bike. How does it handle the trails?

My 28mph speed pedelec operates perfectly fine on 20mph bike paths, because I ride less than 20mph. :) Do we all not believe is personal responsibility and law enforcement of speed limits? Local laws govern path use. "No Motorized Vehicles" implies any ebike or ICE dirt bike/motorcycle...

Sounds like a fun build Ravi. Hi quality parts, high power motor, large battery > kind of like an Optibike but with PAS., and costs much less. That 2.7k must be cost for parts only?

I will concede that the throttle options adds a second dimension of input vs pedal only. I meant awareness when entering an intersection and you can stop pedaling and pay more attention and have instant acceleration if needed. Awareness when starting from from a stop light and you need to get...

Court J- I hear you saying that throttled ebikes are no longer considered bikes, IYO. Thus, you are out of step with the legal definition, HR 727. You may be consistent with the People-For-Bikes separation of classifications, but PFB still qualifiies them as bikes.
