    We = Prius and me. And Mr. Trek is quite often in the back.

    The wind giveth and the wind taketh away.
    Today the wind was NE 10.
    67 deg F in Naperville and Elk Grove.
    33.3 miles , fcd = 62.4 x .943 = 58.8 MPG.
    Tank is still at fcd 70.6 x .943 = 66.6 MPG
    41 miles remaining.

    Today , 69 deg F in Naperville , 71 in Elk Grove.
    Wind SW8.
    33.3 miles, fcd = 694 x .943 = 65.4 MPG.

    Grom : Rode 16.4 miles Sunday , 19.0 on tank , fcd = 178.8.

    Thank you. The Grom is just a very efficent machine. as long as you go slower than 45MPH.

    Just the speed I like to go……or a bit slower. Washington state is so beautiful, moving too fast is a waste. Going east on Highway 2 leading to the Cascade mountains, for about 35 miles I can take backroads along it. Have to get on Highway 2 at two points, but the speed limit is reduced to 50MPH from 60MPH. I can wait till there isn’t traffic & probably go 40-45MPH. Going north & south at 35MPH would give me 100 miles(more?) of terrain to explore. Yeah, if my health (probably not) would let me, I could do the Grom.
    How much torque & HP does the Grom have? Does the Grom bog down on steep slopes? Lot of steep hills around here. I’d hate to have to use maximum power going up a 35-40MPH hill on a continuous basis.
    ///////
    PS…..Oh, I just found out, the engine is a single cylinder, 4-stroke, so the torque should be a bit higher than I thought. The Grom cylinder is about 100cc smaller than each of the two 225cc cylinders on my 450 Suzuki. Could the Grom have 15+HP? The Grom is about half the weight of my old Suzuki. That’s great! Any tipovers, I might be able to pick it up without my back going out. Wouldn’t want to have to pick it up, tho.
    ////////
    PS I…..Oh, just found out. The Grom 9.7 HP provides a bit higher CC/HP than I expected. Its about the same CC/HP as my old Suzuki. Possibly the smaller Grom cylinder, as compared to my 100CC larger Suzuki cylinders, detracts from a lower CC/HP ratio, that new technology has gained over the decades.
    ///////
    PS II…..& now I see a Benelli 135cc, 11.3 HP, 7.4 lbs-ft of torque, competitor to the Grom. Benelli, less torque for less lower speed accelleration, but higher 70MPH speed(maybe) because of the extra HP. The Benelli is 25 lbs heavier than Grom, but vibrates more. Some people have complained about extra vibration due to poor OE tires. Bet the MPG is considerably lower. Sounds like the Benelli doesn’t have as good fit&finish & straight-forward maintenance as the Grom. BUT, the Benelli is cuter with the beautiful Green & after-market items are less necessary. After-market for Grom is better than Benelli. Used pre-2022 Benelli 135’s have 5spd transmissions, whereas Grom’s before 2022, only have 4spds.

    Grom is built in Taiwan(very good), Benelli is made in communist china(always small letters)….very, very bad!

    yes, my Grom has five speeds. That's one reason I waited to get a 2022 model. The approx 10 HP is enough.
    In this part of the state , we don't have many hills. The under-square design ( bore smaller than stroke ) goes
    against the grain in the motorcycle world , but under-square rules in the automotive world for low emissions
    and maximum efficiency

    Today , 68 deg F in Naperville , 69 in Elk Grove , wind W9.
    33.3 miles , fcd =68.2 x .943 = 64.3 MPG.
    Not too bad. Not excellent.

    Too many hills here. I’d love an EV bicycle with their awesome torque. A modern EV bicycle, with only a 2Kilowatt motor & a large Lithium battery, should be able to take that nearby 8degree hill OR give an excellent range. I can’t afford an EV car, so an EV bicycle would be great with a radius of 50miles from home…..if I can find FREE 220Volt EV charging at a distance from home.

    Unfortunately, most EV bicycles do not charge on L2. Even EV motorcycles rarely have L2 charging capability, until recently and for big $$. If you cannot afford a new, less expensive ICE car, you cannot afford one of those EV motorcycles either.

    As for the 2 kW electric motor on an EV bicycle, that's a bit of overkill... Less than 1 kW should be more than enough, unless you're planning on lugging a 100 lb battery with you for your extra long range... :);)

    Also , if you have an e-bike , expect to pedal. Uf you're not already a cyclist , your EV range will suffer.
    I don't have an e-bike , because I WANT to pedal.
    But some e-bikes have a top speed of 30 MPH , which is a bit scary.

    I used to push my pedal bicycle, riding fast downhill to as high as 60MPH. My past EV bike, that was stolen, would go 30+MPH & I had a ball with it. My health says no peddling now.

    No. I had a 2 Kilowatt motor on my EV bicycle, which got stolen. The steepest hills here needed that 2KW motor AND failed to climb that 8Degree hill. An 8degree slope has only a 42+foot horizontal run & already has a rise as high as a 6foot tall person. That is very steep! Modern efficient EV motor windings MAY allow less than 2kW for such a steep hill, but 1kW motor power would be (far?) too little.
    Whatever EV motor you have, you do NOT want to have to floor it all the time (burn-out mode) on the steepest hills.

    PS…..If you think 2kW motors are overkill, there is a 5kW EV bicycle…..as in bicycle, NOT motorcycle.

    The power rating of the motor or engine of a vehicle is far from the only factor determining the steepest grade the vehicle can ascend.

    An 8° slope is steep, but not unusually so. I've climbed steeper hills than than on an inappropriately geared non-motorized bicycle, and I can't sustain 0.2 kw.

    I could output 350Watts. I, on a 10speed nor on the 2kW bicycle could climb the 8degree slope. Later, I re-geared my 10spd & went up the hill. Different electrical windings on the EV motor would have given more torque & might have handled the 8degree slope, but at the cost of about 7MPH off the flat road top speed of my EV bike.
    PS…..The 8degree sloped road is one of 4 within 10 miles of our area. They are all a good huff & puff & well known here.

    From July 11, 2022:
    Oh….now I see a Honda Navi, cute & slightly smaller than the Grom. The Navi has a 110CC 8HP engine, with a carburetor, CVT transmission & $1800 price. Acceleration is most often (always?) accompanied by full throttle at any speed. I bet I can lay off full throttle in many cases. With the CVT & foot braking for both wheels, a beginning rider would be able to simplify their learning curve. Small 12inch (front) & 10inch (rear) scooter steel black wheels & tires. Brakes are drums & inadequate. Also inadequate are the headlight, taillight & gas tank is only 0.9 gallons. Tops out at 45-48MPH (into the 50’s if the wind is blowing with you). A rider weighing a hundred pounds, in a bicycle tucked position & with the wind, may turn the Navi into a barnstormer. Made in Mexico, after first years being built in India. Any hills you need to climb will raise your MPG……because you’ll go so slow, the bumper of the vehicle behind you will push you down the road….despite you going up the hill.
    If the Navi is driven on highways at its top speed (which doesn’t top anything), you may only get 80MPG!
    But it is cute…..I said that already

    Collect and return mother-in-law, 76 to 81°F:
    3.4 miles - 144 Wh/mi or 6.9 Mi/kWh
    3.7 miles - 208 Wh/mi or 4.8 Mi/kWh

    3.7 miles - 235 Wh/mi or 4.3 Mi/kWh

    Monday morning, to free charger, 57°F:
    2.8 miles - 144 Wh/mi or 6.9 Mi/kWh
    36.66 miles added in 44"
    Charger to work:
    19.2 miles - 187 Wh/mi or 5.3 Mi/kWh
    Back home, 61°F:
    19.1 miles - 183 Wh/mi or 5.5 Mi/kWh

    Tuesday morning, to free charger, quite warm for 06:00, 61°F:
    2.8 miles - 104 Wh/mi or 9.6 Mi/kWh
    37.12 miles added in 44"
    Charger to work:

    I agree, even though my own power output is less impressive than yours.

    "Electrically assisted" bicycles border on being oxymorons. The 5-kw "bicycles" Litesong mentioned would be far beyond that border.

    Thanks Red :) and yes sounds like it! (The oxymoron bit!). Our (legal) EV bikes only assist up to 15.5mph.

    Back home last night, 73°F:
    19.1 miles - 183 Wh/mi or 5.5 Mi/kWh

    This morning, to free charger, 61°F:
    2.8 miles - 138 Wh/mi or 7.2 Mi/kWh
    36.6 miles added in 44"
    Charger to work:
    19.2 miles - 202 Wh/mi or 5.0 Mi/kWh
