Performance Test

• The reviewer charged the batteries fully and tested the bike’s speed in different pedal assist levels.
• In throttle-only mode, the bike reached a top speed of 22 miles per hour in pedal assist level 3.
• The distance test was to be conducted later to determine the actual range of the bike.

“The reviewer charged the batteries fully and tested the bike’s speed in different pedal assist levels. In throttle-only mode, the bike reached a top speed of 22 miles per hour in pedal assist level 3.”

Throttle and Pedal Assist Speeds

• The reviewer starts by using throttle only, gradually increasing the throttle assist levels from three to five.
• The bike’s speed is noted at different throttle assist levels, reaching up to 28 miles per hour.
• The reviewer remarks on the need for an eighth gear and the challenge of keeping up with the cadence at higher speeds.

“We are at 25 miles an hour… Throttle only and we are at 27 and a half miles an hour.”

Initial Impressions and Seating Position

• The reviewer comments on the odd battery power drop despite fully charging both batteries.
• The seating position is described as aggressive, resembling an Enduro mountain bike.
• The full suspension is noted to provide a comfortable ride, eliminating the need for a suspension seat post.

“This is an awfully long bike…but the full suspension has made this totally comfortable…I don’t need to do it.”

Regenerative Braking and Battery Life

• The reviewer discovers regenerative braking, as indicated by a small emblem when the brake is used.
• It is mentioned that regenerative braking might not have a significant impact on battery life.
• The technology is appreciated, but no visible effect on the battery’s wattage meter is observed.

“Regenerating to the battery…I like the technology in…although I don’t see it on the wattage meter.”

Rider’s Position and Bike Stability

• The reviewer demonstrates the bike’s tall height compared to their own, showcasing the higher handlebars.
• The width of the handlebars is mentioned, providing stability but encouraging a forward-leaning riding position.
• The full suspension is praised for its ability to absorb bumps effectively.

“And this is how tall it is compared to me…the width of the handlebars…I think it makes it pretty stable.”

Battery and Range Concerns

• The battery level drops to two bars after approximately 10.98 miles of riding.
• Uncertainty arises regarding the remaining range and whether the reviewer will need to rely on pedal power.
• Ambient temperature, rider weight, and pedal assist level are provided as additional context.

“We did have four bars on the battery…if we’ve only got 11 miles, how far are we going to be able to go?”

Uphill Performance with Throttle Only

• The reviewer tests the bike’s torque by riding it uphill using throttle only.
• The bike effortlessly climbs the incline without requiring pedaling.

“This is going pretty easy…I’m not pedaling…not an issue for this bike at all.”

Brake Test

• The reviewer tests the bike’s braking performance for both speed and stopping ability.

“Let’s see how fast we can get this thing going…and how quick it will stop…for a 24, 25.”

Performance and Battery Life

• The reviewer runs back to measure the distance the bike traveled and comments on its weight and difficulty to get going. However, they mention that the bike reached a speed of 26 miles per hour.

“This thing is heavy…that is a lot of weight to get going but we were moving like 26 miles an hour.”

Brake Test

• The reviewer prepares to conduct a second brake test and comments on the previous brake test, mentioning that the bike stopped at the same distance.

“Oh, that’s the same distance…same distance.”

Battery Life Concerns

• The reviewer notes that they have reached 20.34 miles with only one battery bar remaining. They express concern about being far from home and unsure if the bike will make it. They mention using pedal assist and not using the throttle after a hill climb.

“Down to one battery bar left and that concerns me…I’ve been pedaling on pedal assist four to get here.”

Final Battery Range and Display Confusion

• The reviewer reports being able to put about 31 to 32 miles on the bike before the battery went out. They express confusion about the display, mentioning that the battery power shows at an angle and the last bar may cause panic, although it is still a full bar.

“The battery went…it didn’t even go dead…that confuses me.”

Bike Features and Design

• The reviewer compliments the bike’s full suspension and how it enhanced the ride. They also mention that the bike receives positive comments for its appearance and has an “Enduro” feel, with a stretched-out riding position and wider bars.

“This full suspension…helped with the ride…the bike looks cool…has that Enduro feel about it.”

Areas for Improvement

• The reviewer discusses a few aspects they would like to see improved. They mention the shifter, expressing a preference for trigger shifters, and comment on the seat’s comfort after 31 miles. The display is also criticized for being difficult to read in direct sunlight.

“The shifter…I wish it had trigger shifters…the seat…after 31 miles…the display…hard to see when you have direct sunlight.”

Bike Height and Sizing

• The reviewer discusses the bike’s height and sizing. They mention the bar height of 29 inches from the ground, their own height of 5’9″, and the manageability of the bike for a person who is 5’3″. They also demonstrate the maximum extension of the seat post.

“With me at five nine…the bike was manageable…the seat post goes up to…however tall that is that’s how tall you can be to ride this bike.”

Overall Impression and Future Testing

• The reviewer concludes by praising the bike’s performance and expressing excitement for testing it on a mountain bike trail. They mention the usefulness of the second battery for power during inclines. They also encourage viewers to check the link in the description to purchase the bike and support the channel.

“Besides that…this bike did really excellent…can’t wait…to test out this full suspension…on a mountain bike trail…the second battery did come in super handy…if you’re interested in this bike go ahead click the link down in the description below.”
