LeMond Prolog: Everything You Need to Know
Current card: $5,795, 26 lb, up to 70 miles, SRAM Apex, a 250W rear hub at 40 Nm. The battery cell on that page also says 250W. Reviews print 250Wh. A 2025 loop measured 21.7 and 38.6 miles.

The short answer
The LeMond Prolog is a carbon flat-bar bike with a rear hub, listed at $5,795. The page prints 26 pounds, 20 mph, 40 newton-meters, and up to 70 miles. The battery cell says 36 volts and 250W. Reviews print 250 watt-hours. A Jan. 2, 2025 loop measured 21.7 and 38.6 miles. Older tags were $4,500, $4,795, and $5,495. No class numeral and no throttle turned up on the card.
The LeMond Prolog is a flat-bar carbon commuter with a rear hub, not the drop-bar sibling and not a train folder. The US product page, in this crawl, is $5,795, with shipping quoted at 6–8 weeks. The hero line is 26 pounds, up to 70 miles, and 20 mph. Detailed specs name a Mahle X35+ rear hub, 250W max, 40 Nm, and a battery cell that reads “Embedded/down tube; 36V, 250W Panasonic.” A Jan. 2, 2025 test prints that pack as 36V, 250Wh. A 2021 first ride and a UK first ride print 250Wh as well. Watts are the motor. Watt-hours are the pack. The row on the list links here.
250W on the battery line, 250Wh in the reviews
LeMond US product page (this crawl), 99 Spokes’ 2025 build, Electric Bike Report (Jan. 2, 2025), Cycling Weekly (2022), Cyclingnews (Feb. 15, 2021), Autocar (Sept. 2, 2021), and a Nov. 16, 2023 write-up. Not averaged.
| What is printed | |
|---|---|
| Price | The live US card: $5,795. The 2025 catalog matches that tag. A 2021 first ride printed a $4,500 base. A 2022 review printed $4,795 after the old tag. A Nov. 2023 write-up printed $5,495, and $5,995 for the drop-bar sibling. A 2021 UK ride printed £4,350. The list’s old $4,500+ floor is that 2021 base, not the cart open now. |
| Weight | The hero and the carbon sentence both say 26 lb. A 2022 shop scale read 27 lb, which that review also printed as 12.2 kg. The marketing kilogram next to 26 lb is 11.8 kg, and the UK ride printed 11.8 kg. Do not publish 26.5. |
| Motor | The live spec block: Mahle X35+ rear hub, 250W max, 40 Nm. The 2025 test names a Mahle M1 rear hub at the same 250W and 40 Nm. The 2021 rides name the X35+ system. This desk is not gluing M1 and X35+ into a third badge. |
| Battery | Live spec cell: 36V, 250W, Panasonic, in the downtube. The 2025 test, the 2021 first ride, and the UK ride all print 250Wh. A watt is not a watt-hour. If the pack is 250Wh at 36V, the amp-hour figure is 250 divided by 36, which is 6.94. That amp-hour number is not printed on these cards. Do not add it to the spec as if the page said it. |
| Range and speed | Live hero: up to 70 miles, and the same page also prints 112 km. Seventy miles is 112.7 km. The 2025 test’s claim band is 40–70 miles, and the measured loops were 21.7 and 38.6 miles with the motor on. A 2022 review printed 45 miles. The 2021 first ride printed 46 miles and 75 km. Seventy-five kilometers is 46.6 miles. The UK ride printed up to 45 miles and assistance to 15.5 mph. The US hero is 20 mph. Fifteen point five is the 25 km/h cap, not 20. |
| What the money buys now | The live group is SRAM Apex, with an 11–44 cassette on the 2025 catalog. The 2021 and 2022 rides were Shimano GRX, 1×11, and they do not agree with each other: 11–40 with a 40-tooth ring, 11–42 with a 40-tooth ring, or a 42-tooth ring. Those are older builds. The FAQ on the live page says this bike and the drop-bar sibling share a frame. The bars are the split. A throttle did not turn up. A class numeral did not turn up. Rider limit on the 2025 test and the catalog frame note: 250 lb. |
Twenty-six pounds is the claim. Twenty-seven is one shop scale. Two hundred fifty watts is the hub rating. Two hundred fifty watt-hours is what three write-ups call the pack. Publishing one number for both is how a motor becomes a battery. The measured loops, 21.7 and 38.6, sit under the 40-mile floor of that test’s own claim band. They were not averaged with 70.
The spec line says 250W on the battery. Three reviews say 250Wh. A watt is not a watt-hour.
Who it is for
It is the light carbon commuter you can lift, at $5,795 and a 6–8 week ship note, with pedals and a 20 mph US hero. It is not the drop-bar sibling. It is not a Monarc Tracer, which is the aluminum commuter that ships two packs and a thumb. It is not a Urtopia Carbon Joy, which is the 20×3 utility carbon with a throttle on the card. A Roadster V3 is the other light city bike on this list, at a different motor and a different price.
Pedals are here. A thumb did not turn up on the cards read for this guide. Walk the hangtag. If it says Class 1, assist stops at 20. The UK ride’s 15.5 mph cap is 25 km/h, not that sticker. The class chart is the difference. The watt-hour page is why the battery cell’s W is the fight. A rear hub is not a crank motor. The hub versus mid-drive page is that split. Seventy miles is a claim with a rider weight that this crawl did not find on the live hero. The 2025 loops are the measured pair.
Questions people ask
Is the pack 250W or 250Wh?+
The live spec cell says 36V, 250W, Panasonic. A Jan. 2, 2025 test, a 2021 first ride, and a UK ride print 250Wh. A watt is the motor rating. A watt-hour is the pack. Do not publish one number for both.
What does the cart cost now?+
The US page in this crawl is $5,795, with a 6–8 week ship note. A 2021 ride printed $4,500. A 2022 review printed $4,795. A Nov. 2023 write-up printed $5,495. The drop-bar sibling is a different bar on the same frame, not this tag.
How far did the measured loops go?+
The live hero says up to 70 miles, and also prints 112 km. The 2025 test claimed 40–70 and measured 21.7 and 38.6 with the motor on. A 2022 review printed 45 miles. A 2021 ride printed 46 miles. Those were not averaged.
Is 20 mph with no thumb Class 1?+
The US hero is 20 mph. This desk did not find a throttle or a class numeral on the cards. That is the shape of Class 1. A UK ride caps assistance at 15.5 mph, which is 25 km/h. The hangtag is still the shop’s job. The group on the live page is SRAM Apex. Older rides were GRX.

Monarc Tracer: Everything You Need to Know
The cart is $1,899 from $2,508 and includes two 48V 15Ah packs. The spec block says 71 or 73 lb and 65 miles per pack. A June 23, 2026 test scale read 75.5 lb, and that write-up’s claim line said 120 miles.

What Is a Class 1, 2, and 3 E-Bike?
Class 1 is pedal-assist to 20. Class 2 adds a throttle to 20. Class 3 is pedal-assist to 28. A Tuttio is none of these. The sticker is not the trail.
